广晟国际大厦罕遇地震弹塑性时程分析

摘要
采用基于显式积分的弹塑性动力分析方法,对一栋高度约312m超B级高度的超限高层建筑进行了罕遇地震弹塑性时程分析,以了解结构在罕遇地震下的弹塑性行为。结果表明,基于显式积分动力分析法的弹塑性时程分析是保证结构大震不倒的有效方法,本工程采用的框架核心筒结构形式具有较高的抗震承载力和延性,能够满足"大震不倒"的建筑抗震设防目标。
In this paper, the elasto-plastic time-history analysis of a 312m, super-B rating high building under a rare earthquake was carried out by the elasto-plastic dynamic analysis method base on explicit integration, in order to understand the elasto-plastic behaviour of this structure when suffering a rare earthquake. The result showed that the elasto-plastic dynamic analysis method base on explicit integration is an effective approach which could make sure the structure stay up under a rare earthquake, and the frame-coretube structure form applied to this project had a good seismic bearing capacity and ductility which could achieve the third level seismic fortification object of criterion.
