摘要

框架-中心支撑双重抗侧力结构体系中,为检验中国规范中顶部验算法和美国规范中均布验算法的差异性,本文利用SAP2000分别进行6层、12层和16层模型的结构设计,然后利用ABAQUS/Standard进行弹塑性时程分析,得到罕遇地震作用下框架部分的剪力承担率,结果表明,经过顶部验算法验算的低层框架-中心支撑体系,框架在罕遇地震下的剪力分担率大大增加。对于层数较高的框架-中心支撑体系,框架上部的剪力分担率有所增加,而框架下部没有受到明显的影响。
For the interacting system of concentrically braced and moment resisting frames,to compaire the difference between the top checking method and uniform distribution checking method,a six layer,a twelve layer and a sixteen layer structure models were designed using SAP2000,and a elasto-plastic time-history analysis was performed using ABAQUS / standard.The shear-bearing capacity of moment frame of dual systems resisting lateral forces under rare earthquake loads was achieved.The results showed that for the lower layer frame concentrically braced system under top checking method,the shear-bearing capacity of moment frame increased greatly,but for the higher layer frame concentrically braced system,the shear-bearing capacity of upper moment frame increased slightly,the lower moment frame had no obvious effect.
