德阳汇通大厦A栋Ⅱ区建筑结构抗震性能分析

Seismic Performance Analysis of the Area Ⅱ of De Yang Huitong Building A

德阳汇通大厦A栋II区是一个复杂连体结构。为了解结构的抗震性能,确定地震反应时的薄弱部位,提出加强措施,对该结构进行了空间模型下的抗震分析,包括模态分析和大震作用下的弹塑性时程分析,通过对位移、内力、应力等反应数据分析,发现结构满足延性设计要求,无明显薄弱层,抗震性能良好。

The area II of De Yang Huitong Building A is a complex connecting structure. In order to understand the seismic performance of the structure and determine the weak parts, then present enhancement measures, the seismic analysis of the structure under the space model were carried out, which includes model analysis and elastic-plastic time history analysis under major earthquake. At last, it is recognized that the structure can have a good seismic performance by the data of displacement, internal force, and stress.
