摘要
朝阳区霞光里5号、6号商业金融项目位于北京市朝阳区三元桥附近,受建筑平面布局影响,局部框架柱采用搭接柱转换结构。本文总结了搭接柱转换结构的工作原理,以及搭接柱转换设计的要点,同时为保证结构的安全性,运用ABAQUS分析软件,对搭接柱转换节点进行了有限元建模,在大震工况下对关键节点的性能进行了弹塑性有限元分析。结果表明:在大震下,各关键节点除局部单元出现塑性外,节点的整体性能处于弹性状态,满足大震不屈服的抗震性能要求。
No.5 and No.6 commercial and financial projects of Xiaguang Village located near Sanyuan Bridge,Chaoyang District,Beijing.Affected by the layout of the building,some of the frame columns adopt the lapping column transfer structure.This paper summarized the working principle and the key design points of the lapping column transfer structure.Besides,in order to ensure the safety of the structure,the ABAQUS analysis software was applied to establish the finite element model of the lapping column transfer node,and the elastoplastic finite element analysis was carried out on the performance of the key nodes under the condition of large earthquake.The results showed that the overall performance of the key nodes was in an elastic state except for some local elements under the large earthquakes,which can meet the seismic performance requirements of the large earthquakes.
