Development of Nonlinear Geometric Seismic Isolation with a Duffing Spring

Scientific journal, Seismic isolation is widely used in several countries, and the number of seismically isolated buildings has increased rapidly in recent decades. Seismic isolation extends the natural period of a building to decrease the absolute acceleration and seismic force. As there is a trade-off between the absolute acceleration and displacement, a soft layer results in a large displacement for a large seismic wave, but the hard one causes the large absolute acceleration even for a small seismic wave. The restoring force of a Duffing spring is given by the third and first orders of the displacement. This spring has been applied to protect a building from large earthquake waves. However, the influence of the coefficient of the Duffing spring that determines the dynamic characteristics of the system has not been clarified. Thus, a used Duffing spring may not be appropriate for seismic resistance. Moreover, most studies are based on analytical methods, and the advantages of the Duffing isolation have not been verified in an actual system. To address these problems, this paper reveals the influence of the coefficient of the Duffing spring on structural responses to seismic waves. Moreover, this paper devised a way to implement a Duffing spring for seismic isolation and carried out experiments to verify the validity in actual systems. The experimental results presented that the Duffing spring was effective in protecting a building in actual systems.

AN EXPERIMENTAL STUDY ON PRACTICAL USE OF A LEAD RUBBER BEARING WITH FAIL-SAFE MECHANISM

Journal of Structural and Construction Engineering (Transactions of AIJ), 83, 749, 1009, 1019, Architectural Institute of Japan, Jul. 2018, [Peer-reviewed], [Domestic magazines]
Japanese, Scientific journal, The authors have been developing a new seismic isolation bearing, which consists of a lead rubber bearing (LRB) and a slider bearing as a fail-safe (FS) mechanism in series. The bearing called “FSLRB” behaves as a general LRB which is just friction connected to the building structure at either of upper or lower end, when subjected to design level earthquakes or smaller, while the sliding behavior keeps LRB away from giving excessive hardening and shear break in severe earthquakes beyond expectations. Hence, FSLRB has much higher seismic safety compared to general isolation bearings including conventional LRBs. In this paper, dynamic and quasi-static horizontal loading tests under constant or varying compressive loadings for several kinds of scaled and full-scale FSLRB specimens are conducted, to evaluate the effect of bi-directional excitations on additional torsion in the LRB part and changes in friction properties in the slider part. Ultimate performance limit of a full-scale bearing is also investigated under extremely high surface pressures beyond expectations.
 Dynamic loading tests of two types of □-200mm scaled specimens, each has different second shape factor in the LRB part, make clear that there is no apparent difference in friction properties between uni-directional and bi-directional excitations, and no damage to the LRB part due to the torsional behavior in bi-directional excitation, as far as the bearing is applied under a reasonable surface pressure around 10 N/mm². Bi-directional dynamic loading tests of a □-900mm full-scale specimen show that there is no significant scale-effect between the full-scale FSLRB and the □-200mm scaled one on both the torsional behavior of the LRB part and friction properties of the slider part. Uni-directional dynamic loading tests of □-600mm full-scale specimens indicate that dynamic and static friction coefficients have quite low velocity dependence in reasonable sliding speed expected in the practical use. Finally, uni-directional quasi-static loading tests of □-600mm specimens show that the bearing should be applied under surface pressure of 20 N/mm² or lower, to give a well-ordered tri-linear hysteresis curve without causing any unexpected incidents such as partial uplift of the slider part and buckling or shear break of the LRB part.
 Furthermore, surface pressure dependence of dynamic and static friction coefficients are inductively estimated applying all the data obtained in the series of the research, including the test results of □-60mm scaled slider, □-414mm scaled FSLRB and □-900mm full-scale FSLRB introduced in the authors’ preceding paper. The data indicate that both dynamic and static friction coefficients are highly affected by the dimensions of each FSLRB, those are the second shape factor of the LRB part and out-of-plane stiffness of the steel plates between the LRB part and the slider part. By introducing “effective surface pressure” reflecting the effect of the above two dimensions, friction coefficients can be even accurately estimated compared to a conventional method only using mean surface pressure.
 As a conclusion through the series of the loading tests and the considerations mentioned above, the authors think that FSLRB is ready for the practical use in a seismic isolation system with even higher safety margin compared to conventional systems., 11047912

A proposal of An Isolation System with Higher Seismic Safety against Input Ground Motions beyond Expectations

English, International conference proceedings, Since seismically isolated (SI) buildings are thought to be fragile when subjected to extreme input ground motions beyond design level, various measures such as shock absorbers on moat walls and stoppers put in isolation level have been developed. Those technologies should be helpful to increase seismic safety margin of SI buildings, while they cannot avoid the damage to moat walls, superstructure, or isolation devices. In this paper, the authors propose a new lead rubber bearing (LRB) which has much higher seismic safety compared to general isolation bearings including conventional LRBs.
 The proposed bearing named “FSLRB” or “Fail-Safe LRB” consists of a conventional LRB and a newly developed slider system in series. Friction factor of the slider system is optimally provided to start sliding just before LRB gives a hardening property with the shear strain of around 250%. Then, the bearing behaves as a general LRB which is just friction connected to the building structure at either of upper or lower end, when subjected to design level earthquakes or smaller, while the sliding behavior keeps LRB away from hardening and shear break in severe earthquakes beyond expectations. Hence, supporting a superstructure only by the proposed bearings will enable the whole SI building to protect from any structural damage regardless of the input ground motion levels. A preliminary time history analysis for two SI building models, one applying only FSLRBs, the other applying only conventional LRBs, shows the advantages of the system with the proposed bearings.
 Realizing the above high seismic performance, firstly the most suitable slider material, which was a certain PTFE, was selected by conducting a series of dynamic loading test for each combination of stainless steel plate (SUS304) and 12 candidate slider materials. A dynamic loading test of a scaled FSLRB applying the selected PTFE showed that the bearing almost behaved as expected in the preliminary time history analysis. Dynamic and static friction factors were evaluated as well as surface pressure and velocity dependence of those two factors were formulated from the test results. Furthermore, a full-scale FSLRB was tested under a rather high compression force with quasi-static horizontal loading, to investigate the maximum allowable conditions regarding surface pressure and the second shape factor of LRB part. Finally, a detailed time history analysis of a FSLRB building model was conducted. As for the analysis model, 256 full-size FSLRBs with the mechanical properties evaluated in the above loading tests supported a deformed nuclear power plant consisted of a reactor building and a turbine building set on a common isolation raft. The analysis result showed that the superstructure remained elastic and the maximum responses were lower than design criteria even when subjected to a long-period ground motion beyond design level. On the other hand, it became clear that both the maximum deformation and residual deformation at isolation level were much larger than conventional LRB building model.
  From the above development and analyses, it can be finally concluded that an SI building applying the proposed bearings can realize much higher seismic safety compared to conventional SI buildings, if only provided a large enough isolation gap considering the maximum considered earthquakes., 11047912

Japanese, As a new damper which is suited to seismic retrofit for existing high-rise buildings, the authors have developed a passive variable friction damper (VFD) with displacement dependent damping force characteristics. In the present paper, in order to evaluate the response control effects of high-rise buildings incorporating VFDs, earthquake response analyses were conducted using thirty-story frame structure models with VFDs, with conventional friction dampers, or without dampers. The results indicated that VFDs can mitigate response story shear forces and column axial forces compared with conventional friction dampers.

Journal of structural engineering. B, 53B, 9, 16, Architectural Institute of Japan, Mar. 2007, [Peer-reviewed], [Domestic magazines]
Japanese, An analytical model for lead-rubber bearings is proposed to predict bearing force-displacement behavior under extremely large deformation. Static loading tests of a lead-rubber bearing under a range of axial loads were performed to assist in the development of a new hysteresis model for large shear deformation behavior. The hysteresis model is combined with the mechanical model based on the two-spring model previously proposed by Koh and Kelly. The bearing test results showed that the mechanical properties, such as changes in shear stiffness and buckling characteristics, varied with the applied axial load. The proposed model can successfully predict a variety of force-displacement relationships for lead-rubber bearings taking into account the level of applied axial load.

SEISMIC HAZARD ANALYSIS BASED ON FAULT RUPTURE SCENARIOS AND THEIR OCCURRENCE PROBABILITY : For implementation of strong ground motions predicted by fault models in performance-based design of structures
DAN Kazuo, KAMBARA Hiroshi, FUJIKAWA Satoshi, KIKUCHI Masaru
Journal of Structural and Construction Engineering (Transactions of AIJ), 71, 602, 119, 128, Architectural Institute of Japan, Apr. 2006, [Peer-reviewed], [Domestic magazines]
Japanese, Prediction technique of strong ground motions has been intensively developed in Japan since the 1995 Hyogo-Ken Nanbu earthquake (M_J 7.3), and it has been applied to the practical prediction for inland earthquakes and plate-boundary earthquakes by Japanese Government. On the other hand, recent earthquakes of the 2001 Geiyo earthquake (M_J 6.4) and the 2004 Mid Niigata prefecture earthquake (M_J 6.8) arose not only requirements of safety of lives and structural elements but also requirements of function of equipments and industrial lines. These requirements are well realized in the performance-based design of structures. Hence, we proposed a method of seismic hazard analysis based on fault rupture scenarios and their occurrence probability for implementation of strong ground motions predicted by fault models in performance-based design of structures.

LARGE DEFLECTION/POST PEAK ANALYSIS OF REINFORCED CONCRETE SLABS CONSIDERING THE EFFECT OF BOND-SLIP OF REINFORCEMENT
MIZUNO Masae, UEDA Masaiki, KOSHIKAWA Takeaki, KIKUCHI Masaru
Journal of Structural and Construction Engineering (Transactions of AIJ), 71, 602, 153, 160, Architectural Institute of Japan, Apr. 2006, [Peer-reviewed], [Domestic magazines]
Japanese, This paper deals with the large deflection analysis of reinforced concrete slabs considering the effect of bond slip of reinforcement. Johansen's yield-line theory is well known method of calculating the ultimate strength of RC slab. However, it under-estimates the ultimate strength of slabs which have fixed edges because of the membrane stress. In order to take it into account, geometrical nonlinearity should be considered. In this paper, we propose the method of large deflection analysis which is based on Murray and Wilson's method. In order to verify the analytical method, three numerical examples are given and the results are compared with the experimental results.

NON-LINEAR STEADY-STATE VIBRATION OF SEISMICALLY-ISOLATED STRUCTURES WITH HYSTERETICALLY-DAMPED ISOLATION SYSTEM
KIKUCHI Masaru, YAMAMOTO Sachie, TAMURA Kazuo, UEDA Masaiki
Journal of Structural and Construction Engineering (Transactions of AIJ), 70, 592, 75, 82, Architectural Institute of Japan, Jun. 2005, [Peer-reviewed], [Lead author], [Domestic magazines]
Japanese, The study of the steady-state vibration of a system under sinusoidal excitation can provide important insights into the more general dynamic response structures. The response of seismically-isolated structures with viscously-damped isolation system was previously studied by the authors. This paper presents the non-linear steady-state vibration of seismically-isolated structures with hysteretically-damping isolation system. The solution method for the steady-state vibration of the non-linear system is based on the work of Tajimi, and expanded to seismically-isolated structures. The non-linear superstructure behavior is significantly different from that of fixed-base structure. Consequently, the important aspects for isolated structure design is highlighted.

Journal of Structural and Construction Engineering (Transactions of AIJ), 70, 588, 95, 102, Architectural Institute of Japan, Jan. 2005, [Peer-reviewed], [Domestic magazines]
Japanese, The use of flat-plate structures have increased because this type of structure can realize optimum and flexible space utilization. In the application of flat-plate structures, slab resonance should be an important consideration, because of potential problems such as incorrect operation of equipment in manufacturing facilities or occupant discomfort in residential structures. However there are few studies on the free vibration analysis of slabs within flat-plate structures. In this paper, the free vibration analyses of plates with columns resting on lateral, rotational and torsional elastic edge supports uniformly are carried out by use of the superposition method based on the Mindlin plate theory. In order to study the vibration properties of the plate, column size, plate aspect ratio and plate thickness ratio are set up as evaluation parameters.

Journal of Structural and Construction Engineering (Transactions of AIJ), 69, 580, 69, 76, Architectural Institute of Japan, 2004, [Peer-reviewed], [Domestic magazines]
Japanese, The large deformation/post-peak behavior analysis method of concrete beams and columns considering bond-slip of reinforcement is developed. The analytical procedure is capable of predicting the response of concrete beams and columns under axial force and biaxial bending in the material and geometrical nonlinear domains, including post-peak behavior using the incremental arch length method. The paper gives an outline of the nonlinear analysis method which includes the effect of bond-slip of reinforcement to handle the large deformation region, and three numerical examples are given to illustrate the use of the proposed procedure.

AN ANALYTICAL MODEL FOR SEISMIC ISOLATION DEVICES WITH HYSTERETIC DAMPING
KIKUCHI Masaru, KITAMURA Yoshihisa, INOUE Keiichi, UEDA Masaiki
Journal of Structural and Construction Engineering (Transactions of AIJ), 68, 565, 63, 71, Architectural Institute of Japan, 2003, [Peer-reviewed], [Domestic magazines]
Japanese, Scientific journal, For the purpose of accurately predicting the seismic response of an isolated building, an analytical model for seismic isolation devices with hysteretic damping is proposed. The proposed model is capable of well-predicting the force-displacement relationships of various different types of devices, high-damping rubber bearings, lead-rubber bearings, and two types of steel dampers. Seismic response analyses are conducted to study the effectiveness of both existing models and the proposed model. The responses given by the existing models are mostly conservative. This fact indicates that the proposed model can be used to evaluate the performance of isolation devices accurately and effectively.

MATERIAL NONLINEAR ANALYSIS OF REINFORCED CONCRETE SLABS CONSIDERING THE EFFECT OF BOND-SLIP OF REINFORCEMENT

Journal of Structural and Construction Engineering (Transactions of AIJ), 68, 569, 55, 63, Architectural Institute of Japan, 2003, [Peer-reviewed], [Domestic magazines]
Japanese, Scientific journal, This paper deals with the material nonlinear analysis of reinforced concrete slabs considering the effect of bond slip of reinforcement. Only a small number of studies have been reported in the literature that approximately consider the effect of reinforcement bond slip in two-way reinforced concrete slabs, and almost no cases are found in which material nonlinear analysis is used to rigorously consider the effect. In this paper a potential energy functional is first derived, and then a finite element formulation of the problem is implemented. In order to verify the analytical method five numerical examples are given and the results compared with experimental results.

Japanese, Scientific journal, This paper describes the vertical behavior of elastomeric isolation bearings. A study consists of three phases. In the first phase, dynamic loading tests are conducted. Two types of high-damping rubber bearings which differ in thickness of flange-plates are used. Second, finite element analyses are performed to simulate the test results. Both the tests and the analysis results show that the flange-plates has significant effect on tension modulus. Third, a hysteresis model is proposed. Good agreement between the experimental and the analysis results shows that the model can be an effective numerical tool to predict the seismic response of isolated buildings.

Japanese, Scientific journal, Four buildings at the Kushiro Technical High School, damaged in the 1993 Kushiro-Oki and the 1994 Hokkaido-Toho-Oki earthquakes, were modeled as an assembly of nonlinear elements to verify our present techniques for earthquake-resistant design of structures. The input motions were independently evaluated based on the strong motions recorded on the ground at the Kushiro District Meteorological Observatory, 2km west of the school, and the soil-structure interaction was taken into account. The results of the dynamic response analysis showed a good agreement with the detail of different degree of the damage to the four buildings.

Japanese, Scientific journal, A very large acceleration of 1.6 g was observed on the first floor of the Meiwa Elementary School, Hokkaido, during the largest aftershock of the 1993 Hokkaido-Nansei-Oki earthquake. In order to investigate the cause of this very large acceleration, this paper described the building three-dimensionally as an assembly of nonlinear elements because its plan was not a simple rectangle, and then the base-rock motions were estimated at a depth of 8.6 m after evaluating the soil-structure interaction. The resultant base-rock motions made it clear that the large acceleration of 1.6 g was ascribed mainly to the amplification factor of up to 30 at about 4 Hz from the base rock to the first floor of the building.

SAFETY EVALUATION OF BASE-ISOLATED STRUCTURES

Journal of Structural and Construction Engineering (Transactions of AIJ), 60, 470, 65, 73, Architectural Institute of Japan, 1995, [Peer-reviewed], [Lead author], [Domestic magazines]
Japanese, Scientific journal, This paper describes a series of seismic fragility analyses of base-isolated structures considering non-linear superstructure behavior. The Latin hypercube sampling technique is applied to construct a series of samples that explicitly account for non-Linear behavior. Fragility curves are generated that evaluate the limit state based on maximum superstructure ductility ratio. The study shows that base-isolation systems have a significant advantage for seismic protection compared with fixed-base structures. However, careful consideration should be given to the fact that plastic deformation demands on the superstructure can increase dramatically after yielding if the super-structure is designed anticipating a reduced seismic lateral shear force.

Japanese, Scientific journal, This paper describes earthquake simulator tests of a 1/2.5-scale model of an existing base-isolated, three-story reinforced-concrete building. Two types of high-damping rubber bearings and one type of lead-rubber bearing were used in these tests. Moderate and extreme input motions were applied to the model to study the ultimate behavior of the isolated structure. Dynamic analyses were conducted to simulate the response to both moderate and extreme input tests, using a previously-developed analytical model. Good agreement between the experimental and analytical results was obtained, and the analytical model was confirmed to be suitable for representing the mechanical properties of bearings.

STRUCTURAL DAMAGE POTENTIAL OF STRONG-MOTION RECORDS AT THE KUSHIRO DISTRICT METEOROLOGICAL OBSERVATORY FROM THE 1993 KUSHIRO-OKIEARTHQUAKE (M7.8)

English, Scientific journal, The strong-motion records at the Kushiro District Meteorological Observatory from the 1993 Kushiro-Oki earthquake were applied to rigid-frame structures of different types. The total plastic energy dissipation of short period structures under the records was larger than that under the design input motions, while the energy dissipation of long period structures was comparable or smaller. The response level-of a low building with a short natural period showed that the damage should be moderate or severe. But, the actual damage to such a kind of buildings was rather slight around the observatory. The earthquake resistant capacity of non-structural components should be appropriately evaluated in design process.

Seismic hazard analysis based on fault rupture scenarios and their occurrence probability
DAN Kazuo, KAMBARA Hiroshi, FUJIKAWA Satoshi, KIKUCHI Masaru, J. Struct. Constr. Eng., AIJ, 71, 602, 119, 128, 2006
Prediction technique of strong ground motions has been intensively developed in Japan since the 1995 Hyogo-Ken Nanbu earthquake (M_J 7.3), and it has been applied to the practical prediction for inland earthquakes and plate-boundary earthquakes by Japanese Government. On the other hand, recent earthquakes of the 2001 Geiyo earthquake (M_J 6.4) and the 2004 Mid Niigata prefecture earthquake (M_J 6.8) arose not only requirements of safety of lives and structural elements but also requirements of function of equipments and industrial lines. These requirements are well realized in the performance-based design of structures. Hence, we proposed a method of seismic hazard analysis based on fault rupture scenarios and their occurrence probability for implementation of strong ground motions predicted by fault models in performance-based design of structures., Architectural Institute of Japan, Japanese

Non-linear steady-state vibration of seismically-isolated structures with hysteretically-damped isolation system
KIKUCHI Masaru, YAMAMOTO Sachie, TAMURA Kazuo, UEDA Masaiki, J. Struct. Constr. Eng., AIJ, 70, 592, 75, 82, 2005
The study of the steady-state vibration of a system under sinusoidal excitation can provide important insights into the more general dynamic response structures. The response of seismically-isolated structures with viscously-damped isolation system was previously studied by the authors. This paper presents the non-linear steady-state vibration of seismically-isolated structures with hysteretically-damping isolation system. The solution method for the steady-state vibration of the non-linear system is based on the work of Tajimi, and expanded to seismically-isolated structures. The non-linear superstructure behavior is significantly different from that of fixed-base structure. Consequently, the important aspects for isolated structure design is highlighted., Architectural Institute of Japan, Japanese

Free vibration analysis of slabs in flat plate structures resting on uniformly elastic edge supports
OHYA Fumito, UEDA Masaiki, UCHIYAMA Takeshi, KIKUCHI Masaru, J. Struct. Constr. Eng., AIJ, 70, 588, 95, 102, 2005
The use of flat-plate structures have increased because this type of structure can realize optimum and flexible space utilization. In the application of flat-plate structures, slab resonance should be an important consideration, because of potential problems such as incorrect operation of equipment in manufacturing facilities or occupant discomfort in residential structures. However there are few studies on the free vibration analysis of slabs within flat-plate structures. In this paper, the free vibration analyses of plates with columns resting on lateral, rotational and torsional elastic edge supports uniformly are carried out by use of the superposition method based on the Mindlin plate theory. In order to study the vibration properties of the plate, column size, plate aspect ratio and plate thickness ratio are set up as evaluation parameters., Architectural Institute of Japan, Japanese

Material nonlinear analysis of reinforced concrete slabs considering the effect of bond-slip of reinforcement
MIZUNO Masae, UEDA Masaiki, KIKUCHI Masaru, UCHIYAMA Takeshi, J. Struct. Constr. Eng., AIJ, 68, 569, 55, 63, 2003
This paper deals with the material nonlinear analysis of reinforced concrete slabs considering the effect of bond slip of reinforcement. Only a small number of studies have been reported in the literature that approximately consider the effect of reinforcement bond slip in two-way reinforced concrete slabs, and almost no cases are found in which material nonlinear analysis is used to rigorously consider the effect. In this paper a potential energy functional is first derived, and then a finite element formulation of the problem is implemented. In order to verify the analytical method five numerical examples are given and the results compared with experimental results., Architectural Institute of Japan, Japanese

An analytical model for seismic isolation devices with hysteretic damping
KIKUCHI Masaru, KITAMURA Yoshihisa, INOUE Keiichi, UEDA Masaiki, J. Struct. Constr. Eng., AIJ, 68, 565, 63, 71, 2003
For the purpose of accurately predicting the seismic response of an isolated building, an analytical model for seismic isolation devices with hysteretic damping is proposed. The proposed model is capable of well-predicting the force-displacement relationships of various different types of devices, high-damping rubber bearings, lead-rubber bearings, and two types of steel dampers. Seismic response analyses are conducted to study the effectiveness of both existing models and the proposed model. The responses given by the existing models are mostly conservative. This fact indicates that the proposed model can be used to evaluate the performance of isolation devices accurately and effectively., Architectural Institute of Japan, Japanese

This paper describes the vertical behavior of elastomeric isolation bearings. A study consists of three phases. In the first phase, dynamic loading tests are conducted. Two types of high-damping rubber bearings which differ in thickness of flange-plates are used. Second, finite element analyses are performed to simulate the test results. Both the tests and the analysis results show that the flange-plates has significant effect on tension modulus. Third, a hysteresis model is proposed. Good agreement between the experimental and the analysis results shows that the model can be an effective numerical tool to predict the seismic response of isolated buildings., Architectural Institute of Japan, Japanese

Four buildings at the Kushiro Technical High School, damaged in the 1993 Kushiro-Oki and the 1994 Hokkaido-Toho-Oki earthquakes, were modeled as an assembly of nonlinear elements to verify our present techniques for earthquake-resistant design of structures. The input motions were independently evaluated based on the strong motions recorded on the ground at the Kushiro District Meteorological Observatory, 2km west of the school, and the soil-structure interaction was taken into account. The results of the dynamic response analysis showed a good agreement with the detail of different degree of the damage to the four buildings., Architectural Institute of Japan, Japanese

STUDY ON LARGE-ACCELERATION MOTIONS RECORDED DURING THE LARGEST AFTERSHOCK (M6.5) OF THE 1993 HOKKAIDO-NANSEI-OKI EARTHQUAKE

A very large acceleration of 1.6 g was observed on the first floor of the Meiwa Elementary School, Hokkaido, during the largest aftershock of the 1993 Hokkaido-Nansei-Oki earthquake. In order to investigate the cause of this very large acceleration, this paper described the building three-dimensionally as an assembly of nonlinear elements because its plan was not a simple rectangle, and then the base-rock motions were estimated at a depth of 8.6 m after evaluating the soil-structure interaction. The resultant base-rock motions made it clear that the large acceleration of 1.6 g was ascribed mainly to the amplification factor of up to 30 at about 4 Hz from the base rock to the first floor of the building., Architectural Institute of Japan, Japanese

This paper describes earthquake simulator tests of a 1/2.5-scale model of an existing base-isolated, three-story reinforced-concrete building. Two types of high-damping rubber bearings and one type of lead-rubber bearing were used in these tests. Moderate and extreme input motions were applied to the model to study the ultimate behavior of the isolated structure. Dynamic analyses were conducted to simulate the response to both moderate and extreme input tests, using a previously-developed analytical model. Good agreement between the experimental and analytical results was obtained, and the analytical model was confirmed to be suitable for representing the mechanical properties of bearings., Architectural Institute of Japan, English

STRUCTURAL DAMAGE POTENTIAL OF STRONG-MOTION RECORDS AT THE KUSHIRO DISTRICT METEOROLOGICAL OBSERVATORY FROM THE 1993 KUSHIRO-OKIEARTHQUAKE (M7.8)
DAN Kazuo, WATANABE Koichi, KIKUCHI Masaru, EBIHARA Manabu, Journal of structural and construction engineering, 454, 54, 60, 1993
The strong-motion records at the Kushiro District Meteorological Observatory from the 1993 Kushiro-Oki earthquake were applied to rigid-frame structures of different types. The total plastic energy dissipation of short period structures under the records was larger than that under the design input motions, while the energy dissipation of long period structures was comparable or smaller. The response level-of a low building with a short natural period showed that the damage should be moderate or severe. But, the actual damage to such a kind of buildings was rather slight around the observatory. The earthquake resistant capacity of non-structural components should be appropriately evaluated in design process., Architectural Institute of Japan, Japanese

Takahashi Hiroaki
Comprehensive investigation on the 2018 Hokkaido Eastern Iburi earthquake and its disaster was conducted. Mainshock rupture initiated at deepest part and major slip was occurred in 20-30km deep. Multiple simultaneous landslides in Atsuma town was induced by combination of strong ground shaking and weak sliding layer between pyroclastic fall deposit layers. Halloysite cray minerals was discovered in all sliding layers. Simulation suggested landslides might attack residential houses within 6 seconds. Observed peak ground motions in nearby area were larger than common distance attenuation model. Severe wooden house damage in Mukawa town was due to amplified seismic waves due to site effects. Sounding and boring investigation revealed filled low-density volcanic ash and higher groundwater level in liquefaction area. Electricity blackout caused severe damage in social and economic activities of Hokkaido. These scientific outcomes were explained to residents at public briefing session.
