[提要] 通过采用静力弹塑性分析(push-over)方法对框架&剪力墙结构进行全过程分析,考察了不同刚度特征值、不同楼层数、不同侧移允许值对于考虑剪力墙刚度退化时框&剪结构内力的影响,其中楼层数的影响并不大,而刚度特征值是影响内力分配的重要因素。[关键词] 框架-剪力墙; 内力分配; 静力弹塑性分析Abstract: Push-over analyses are applied for the complete responses of frame-wall buildings.The effects of structural walls on the elastic-plastic responses of frame-wall buildings are mainly investigated.The disciplinary conclusions are drawn by examining the responses of buildings with different stiff character coefficient,different number of stories and different of story drift allowance.The most important factor is stiff characteristic coefficient,while the number of stories contributes 1ittle to the distribution of internal forces.Keywords:frame-wall buildings; internal forces distribution; static push over analyses
