Japanese, When braced moment frames are subjected to a strong ground motion, the bracing elements are likely to fracture. Such fracture results in a large cumulative plastic deformation at the beam end which leads to the connection failure. The authors have proposed a method to assess the brace and beam end fracture using time history response analysis without micro element FEM. However, this method does not take the beam end joint efficiency into account. In this study, the effect of the joint efficiency on the cumulative deformation capacity of the beam end is investigated. Using those results, the seismic performance of the braced moment frame is analyzed including the fracture of brace members and beam ends. - Analysis of gymnasium with angle braces damaged in 2011 Tohoku earthquake and investigation of response controlled retrofit effects

Japanese, Tubular sections are commonly used for truss structures or diagonal braces, because they have higher moment-of-inertia comparing to H-sections or L-sections with the same area. However, their cumulative cyclic deformation capacity after buckling is known as quite small, because high strain concentration appears at local elbow buckling. To improve the performance of such members, the authors have proposed retrofit method to add outer tube and in-filled mortar in-between, as buckling restrainer. In this paper, cumulative cyclic deformation capacity of this member is researched by cyclic loading tests with various thickness ratios and strain amplitudes. Their strain concentration mechanism is also researched thorough various analyses, followed by proposing the concept of strain concentration index. The easy evaluation method for cumulative deformation capacity and energy dissipation capacity is proposed using this index. - An experimental study on cumulative cyclic deformation capacity of tubular braces with local buckling

Japanese, Tubular sections are commonly used for truss structures or diagonal braces, because they have higher moment-of-inertia comparing to open cross-sections with the same area. However, their cumulative cyclic deformation capacities after buckling are known as quite small comparing to H-sections, because strain concentration occurs with local elbow buckling. For evaluating seismic performances of such structures, cumulative cyclic deformation capacity of braces before fracture is essential. In this paper, cumulative cyclic deformation capacity of tubular braces with local buckling is researched by cyclic loading tests with various slenderness ratios and thickness ratios. Their strain concentration mechanism is researched thorough various analyses, followed by proposing easy evaluation method of cumulative deformation capacity.

Buckling Restrained Braces (BRBs) are commonly used as ductile bracing elements in seismic lateral resistance systems. A key limit state governing BRB behavior is overall flexural buckling. However, when the wall thickness of the restrainer is relatively small compared to the core plates section, the restraint conditions against local buckling of the core plate about its strong axis can be critical for the stability and strength of the BRB. In this study, cyclically-loaded experiments and numerical analyses were carried out using various tube restrainer configurations, and the local buckling restraint conditions are discussed and proposed using these results., Architectural Institute of Japan, Japanese - 22450 Studies on Cumulative Cyclic Deformation Capacity of Tubular Braces with Local Buckling : Part1 Cyclic Loading Tests on Tubular Braces

鋼構造建築物の倒壊過程を実験的に解明する研究目的に沿って、国立研究開発法人防災科学技術研究所の大型耐震実験施設で、2020年11月から12月にかけて、縮尺1/2のパイロット試験体による振動台実験を実施した。防災科学技術研究所の兵庫耐震工学研究センターで、2020年12月に実施された日米共同実験に参加し、次世代型鋼構造システムを開発する研究を推進した。また、倒壊に至る鋼構造の非線形・動的挙動を追跡するコンピュータ解析技術を確立する研究目的に沿って、数値モデル化技術を種々検討した。一連の研究活動で得られた成果は、下記のとおりである。(1)模型実験の設計方法、柱や梁の降伏・破断挙動を測定するための計測・画像収録方法を確立し、2021年度に実施する本実験の準備を固めた。(2)複数の実験から得た、鋼構造架構の非線形動的応答に関する実データを、既往の大規模振動台実験のデータと合わせて、数値解析技術の検証を進めた。特に、破断を模擬するための現状のモデル化手法では、既往の重層架構実験で観察された、部材破断後の部材力再分配を正しく再現できないことを突き止め、今後の課題を特定した。減衰モデルの選択によって、ブレース付架構の応答変位や応答加速度が異なることに注目し、定量的な検討を進めた。(3)部材破断の再現方法を含めて、ブレース付鋼構造架構の解析手法に関する知見を蓄積し、現状のブレース付鋼構造架構が保有する耐震性能を検証した。

災害時における鋼構造物の被災事例は枚挙にいとまがなく,地震や風により崩壊した事例は年々増え続けている。人命を保護するため,局部座屈や部材破断などの不安定現象により,鋼構造物が倒壊しないよう設計手法が体系化されているが,事業継続性や居住快適性が重視されるなど,鋼構造物に対する要求は高度化しつつある。現行の設計体系で規定されていない鋼構造物の性能を迅速に評価できる信頼性の高い手法を,構造設計に携わる実務者が利用できれば,より冗長性の高い社会基盤を構築し得ると考えられる。本研究課題では,設計者の技量や熟練度に依らず,鋼構造物の限界性能を検証できる構造設計手法を提示することを目標としている。
数値解析プログラム整備のため,数値解析によりブレースおよび梁の耐力や塑性変形性能を検証した。梁については,これまで純鉄骨を中心として数値解析モデルを検討し,実構造物で多用される合成梁も含め検討する必要性を実感し,本研究課題に追加した。床スラブの仕様を変えた3種の合成梁に関して載荷実験を実施した。
ブレースの性能を整理したデータベースを構築するため,国内外における90件程度の既往の研究成果を調査し,502体の繰返し荷重を受けるブレース試験体の実績を抽出した。うち多数を占めたH形56体,中空円形62体,中空角形90体の断面を有する試験体のうち,建築基準法上,高い塑性変形能力があるランクに分類された試験体は1割から2割程度と寡少であることを確認した。同ブレースは実務上用いられる頻度は高く,構造性能を検証することが急務であることを再認識した。
構築したデータベースを参照し模型載荷実験では実績の少ない試験体として,断面や端部境界条件が異なる,有効細長比10から20の太短い試験体6体と,有効細長比30と80の試験体2体を製作した。載荷実験に向け実験場を整備し,効率的に模型載荷実験を進められるよう準備した。

In 2016 Kumamoto earthquake, roof members of system truss gymnasiums buckled and ruptured, and some of them fell. The system truss is a structural system widely used in gymnasiums in Japan, however, they are designed to be elastic against the design load, and the bearing capacity margin and collapse behavior against large seismic input have not been clarified. In this study, the collapse mechanism of the system truss roof structure supported by RC frames has been clarified through member tests, truss unit tests, partial frame shaking table tests and analysis. In addition, a construction method to prevent the collapse of the entire roof, the introduction of energy absorbing elements into the bearing to reduce the response, and their design method were proposed, followed by researches on immediate risk assessment based on the measurement of point cloud data after the earthquake.

A facility for thermal power generation is one of the most important urban infrastructures. Steel structures are typically used for the facility. This kind of facilities necessary to support heavy masses such as a boiler, which in turn lead to high axial load of steel columns. This study presents the strength and ductility of the steel columns subjected to high axial load based on physical tests of members. A phenomenological fiber element was proposed to reproduce the local buckling-induced softening of those steel columns reasonably. The number of elements of the phenomenological fiber element was relatively less than that of the finite element analysis with shell elements. A numerical program for time history response analysis was developed using the phenomenological fiber element to assess the seismic performance of the facilities with heavy masses. The program was validated by a past shake table test of a 4-story steel moment frame including local buckling-induced softening.

Numerous steel roof bearings in RC gymnasiums were damaged at the 2011 Tohoku Earthquake. These damages are considered to be mainly due to out-of-plane response of cantilevered RC walls; however, their mechanisms are not clear.
In this research, complicated response characteristics of these roof and RC walls are made clear. The real scale mock-up experiments of PTFE sliding bearings, friction damper bearings, and rubber sheet bearings are carried out, followed by the shaking table test for seismically isolated roofs. From these results, detailed construction methods for eliminating the damages without strengthening the roof, followed by proposing the evaluation methods. Also the steel roofs supported by seismic isolation bearings are investigated, followed by shaking table tests and response evaluations.

In this research, the cumulative deformation capacity of the end of the beam was investigated on the basis of the experimental and numerical data, and an evaluation method for assessing the ultimate state of the high-rise buildings under long period ground motion was proposed. Additionally the lateral bracing requirements for H-section beams under cyclic loading was examined by experiments and numerical analysis. To expand the proposed evaluation method, the cumulative deformation capacity of the circular hollow section T-joints was investigated by experiments and finite element analysis. The seismic performance of buildings under severe ground motion in a range of the dominant natural period of the buildings was examined, using the time history analysis program including fracture of the braces and connections. This analysis results also provide a fragility curve of the buildings including the connection fracture effect.

最終年度となる平成22年度においては,昨年度において構成した三次元構造物を対象とした時刻歴応答解析手法を用いて,ブレース部材の破断を考慮した大地震時におけるブレース付ラーメン骨組のエネルギー吸収性能について分析した。その結果,ブレース部材の破断を考慮した場合のブレース付ラーメン骨組の時刻歴応答およびエネルギー吸収性能は,考慮していない場合に比較して大きな差異を生じることを示した。プレースの部材破断を考慮した場合,骨組の変位応答に大きな差異は見られないものの,柱梁の負担するエネルギー吸収量が大きく増大する例も見られた。本研究では,柱梁のエネルギー吸収性能については対象外としていたが,ブレースの部材破断に伴い柱梁の損傷が増大し,骨組全体のエネルギー吸収性能が大きく低下する可能性があることが確認された。
以上より,既存不適格建物の耐震補強に用いる鋼材ブレースが地震力を受けて破断に至るまでのエネルギー吸収性能を評価し,同ブレースを用いた骨組の大地震時における時刻歴応答およびエネルギー吸収性能を比較検証することが可能となった。これにより,既存不適格建物に想定以上の地震動が入力された場合に必要となる鋼材ブレースの補強量を,より適切に把握できるようになると考えられ,信頼性の高い耐震補強設計法の確立に貢献したものと考えられる。
以上の研究成果は国内外の学術会議および学術雑誌を通して発表しており,多数の研究者との意見交換および交流を密に図ることが出来た。
