【摘要】 为研究复杂结构的抗震能力,采用静力弹塑性方法,对两种托墙转换结构在大震作用下的弹塑性地震反应进行分析,通过对结构的延性、承载能力、塑性铰分布、破坏过程的计算和研究,揭示出采用空腹桁架作为转换构件具有更好的弹塑性抗震性能,并探讨了提高空腹桁架转换结构弹塑性抗震能力的措施。更多还原

【Abstract】 In order to study the seismic performance of complicated structures,the elastic-plastic seismic response of two kinds of transfer structure supporting walls when suffering strong earthquake is analyzed by push-over analysis method.It is revealed that the structure using vierendeel truss as transfer member is excellent in elastic-plastic seismic performance by the calculation and research on its ductility,loading capacity,plastic hinge distribution and destruction process,and the measures to improve the structure’s elastic-plastic seismic performance are also discussed.更多还原
