摘要
以实际工程咸阳超限剪力墙结构设计为例,对超限高层的弹塑性时程分析和抗震性能化设计进行研究。本结构高度为134.78m属于超限B类建筑。根据规范对结构进行抗震性能目标设定,并用MIDAS Gen软件对结构在罕遇地震作用下进行动力弹塑性时程分析和构件耗能情况分析,软件分析结果表明,部分剪力墙出现轻微损坏,少数出现中等破坏、加强区剪力墙受拉损伤较严重、耗能构件损坏大于剪力墙并在阻尼耗能中占比与剪力墙基本相同,满足预期抗震性能目标。
Taking the design of Xianyang transfinite shear wall structure as an example,the elastic-plastic time history analysis and seismic performance-based design of out of gauge high-rise buildings were studied.The height of the structure is 134.78 m,which belongs to class B building beyond the limit.According to the code,the seismic performance target of the structure was set,and the dynamic elastic-plastic time history analysis and energy consumption analysis of the structure under rare earthquake are carried out by MIDAS Gen software.The results show that some shear walls are slightly damaged,a few are medium damage,shear walls in reinforced area are seriously damaged,energy dissipation components are damaged more than shear walls,and the proportion of damping energy consumption is basically the same as that of shear walls,meeting the expected seismic performance objectives.
