某框支-剪力墙住宅结构动力弹塑性分析

摘要

本工程属超B级高度的超限高层建筑结构,采用框支-剪力墙结构体系.采用了基于性能的设计方法,并采用YJK-EP弹塑性分析程序对其进行了罕遇地震作用下的弹塑性动力分析.根据上述分析结果,针对超限项目采取了加强措施.分析结果显示,结构抗震性能优良,结构可达到预期的抗震性能目标C级.%The residence is a super high-rise structure whose height exceeds the limit of B-level requirement in code,it adopts frame-supported shear wall structural system.The performance-based design method was adopted and YJK-EP software was used to conduct the elastic-plastic time-history analysis on the structure under the rare earthquake.According to the above analysis results,measures were adopted to strengthen the design.The analysis results show that the seismic performance of the structure is good and the structure can reach the expected performance objective of level C.
