某超限高层框支剪力墙结构动力和静力弹塑性分析

Inelastic time-history Pushover analysis on a shear-wall structure with staggered floors

以某超高层框支剪力墙结构为例,用三维弹塑性分析软件Perform-3D分别进行了弹塑性时程分析和静力弹塑性分析,将得到的整体反应结果和构件损伤情况进行了对比。结果表明,两种分析均揭示了结构弹塑性反应的基本特点,主要反应指标吻合较好。同时需要指出的是,静力弹塑性分析得到的底部破坏情况较时程分析的结果更为严重,而弹塑性时程分析结果则反映上部楼层的损伤程度更严重。

Inelastic time-history Pushover analysis and static inelastic analysis are both method to calculate structural deformation under rare earthquakes, which have different assumption and would be used in specific conditions. Based on a frame support shear wall structure, both inelastic time-history analysis and static inelastic analysis were used to study its seismic performance. Perform-3D software was used to build model and carry out analysis. The results show that basic characteristies of structural inelastic response could be concluded with those two analysis, some of the response values are quite consistent. While it needs to be pointed out those two analysis methods may get different damage distribution results,
