某大跨连体超限高层建筑结构抗震设计及弹塑性时程分析

摘要

介绍了某办公楼超限高层建筑结构设计及在罕遇地震作用下弹塑性时程分析.采用EPDA计算程序进行罕遇地震作用下的弹塑性时程补充计算分析,以保证该结构的关键构件在罕遇地震作用下保持应有的工作性能,防止连体结构的连续倒塌.%This structure design of a long-span high-rise connected building beyond the code limit is presented,and the elastoplastic timing analysis under severe earthquake is carried out.The software of EPDA is adopted to do the supplemental calculation,so the seismic performance of the main components and preventing collapse of the building under severe earthquake are ensured.
