采用悬臂连廊连接的连体结构抗震性能评价及优化设计研究

Study on the Seismic Performance Evaluation and Optimization Design of Conjoined Structures Connected by Cantilever Corridor

针对连体结构在罕遇地震作用下的动力特性及震害机理进行研究,评价其抗震性能。以某高层商务大楼为例,采用ABAQUS有限元软件建立结构计算模型,分析连体结构在7度罕遇地震条件下的弹塑性时程,观察其在罕遇地震作用下的塑性损伤、内力分布及整体变形情况。根据计算结果,为结构抗震优化设计提出相应建议。

In order to study the dynamic characteristics and damage mechanism of the conjoined structure under rare earthquakes,the seismic performance of conjoined structure is evaluated in this paper. Taking a high-level business building as an example,ABAQUS finite element software is used to establish the structure calculation model.The elastoplastic time analysis of the structure is carried out,to observe the plastic damage,internal force distribution and overall deformation in 7 degree rare earthquake. According to the calculation results,some suggestions for the seismic design are given.
