摘 要:某东塔楼是复杂的超限高层写字楼,需要进行罕遇地震下的动力弹塑性分析。采用通用有限元ABAQUS软件和YJKEP软件进行弹塑性时程分析,通过整体反应指标和构件的损伤情况以此来验证该结构在罕遇地震作用下的抗震性能。结果表明2种软件计算出来的位移均能满足“大震不倒”的设防要求,破坏顺序与破坏程度的规律相似,剪力墙在相同的配筋下ABAQUS软件计算的一片墙体损伤比较严重,滑动支座的滑移量在不同软件出现的最大响应的波不一致,得出复杂结构需要不同的软件进行动力弹塑性对比分析。The East Tower is a complex over-limit high-rise office building that requires dynamic elastoplastic analysis under rare earthquakes.The general finite element ABAQUS software and YJK-EP software are used to analyze the elastoplastic time history.The overall response index and the damage of the component are used to verify the seismic performance of the structure under rare earthquakes.The results show that the displacements calculated by the two software can meet the fortification requirements of“big earthquake does not fall”.The order of failure and the degree of damage are similar.A piece of wall calculated by the ABAQUS software is more severe when the shear wall is under the same reinforcement.However,the maximum response wave of the sliding amount of the sliding support in different software is inconsistent.It is concluded that complex software requires different software for dynamic elastoplastic comparison analysis.
