某框架剪力墙–钢桁架混合结构设计与分析

Design and Analysis of A Framed Shear Wall-steel Truss Hybrid Structure

某高层综合楼建筑采用框架剪力墙-钢桁架混合结构。该工程存在楼板不连续、构件间断及局部不规则等问题。在结构的设计过程中,分别采用SATWE、Midas和PUSH&EPDA软件对结构进行弹性反应谱分析、多遇地震作用下弹性时程分析和静力弹塑性分析,并对结构的关键部位采取了构造加强措施。结果表明,结构的抗震性能良好,各项指标均满足规范要求和C级抗震性能目标。

A high-rise building structure has a structural height of 36.3 m.It adopts framed shear wall-steel truss hybrid structure.The structure has floors discontinuity,component discontinuity and local irregularity,which is ultra-limit building.During the structural design,elastic response spectrum analysis,elastic dynamic time history analysis under frequent earthquakes and static elastic-plastic analysis were carried out by SATWE,Midas and PUSH&EPDA respectively,and structural reinforcement measures were taken for key positions of the structure.The results show that the structure has good seismic performance.All the indexes of the structure can meet the requirements of the code and C-level seismic performance target.
