带转换斜柱的框剪结构弹塑性时程分析

Elasto-plastic Time-history Analysis of Frame Shear Structure with Transfer Inclined Column

采用非线性程序ABAQUS对某带斜柱转换的框剪结构进行弹塑性时程分析,其特点是裙房大跨度框架结构首层设计12根转换斜柱跨越2层与4层柱连接,柱高16.4m。通过对转换梁方案和转换斜柱方案的分析对比,针对转换斜柱方案找出结构薄弱位置并分析结构在罕遇地震下的抗震性能,为抗震设计提供依据。

ABAQUS software is adopted to execute nonlinear time-history analysis for a Frame shear structure with transfer inclined column. The long-span frame structure of podium is composed of the first layer of 12 pillar of transfer inclined column,which is 16.4 meters tall cross over to layer 2 and connect with the fourth floor columns. And two schemes of transfer beam and transfer inclined column were analyzed and compared. Based on transfer inclined column scheme,the weak parts is defined and seismic performance is analyzed under strong earthquake, which can be referred to the seismic design.
