摘要
基于Perform-3D软件,输入3条地震波对工程实例进行动力弹塑性分析,以ASCE 41规定的构件弹塑性变形量化指标作为可接受准则,对工程实例进行抗震性能评估,结果表明在罕遇地震作用下结构刚度降低有限,结构处于弱非线性状态;层间位移角等性能指标均满足规范要求,满足"强柱弱梁"等设计要求;剪力墙、框架梁(连梁)等构件比预期性能目标好,结构处于运行控制性能阶段,有较多的安全储备。
Based on the Perform-3D software, the dynamic nonlinear analysis is carried out for the engineering example by inputting three seismic waves. The seismic performance of an engineering example is assessed based on Perform-3D which refer to the acceptable criteria of elastoplastic deformation of ASCE 41. The dynamic nonlinear analysis results show that few structure stiffness to reduce under rare occurred earthquakes, and the structure in the weakly nonlinear state. The elastoplastic floor drifts and other performance targets are qualified to specification requirements. The structure meets specification ＂column is better than beam＂ and other related anti-seismic concept design requirements. And it is concluded that shear wall, frame beam, frame column, conversion truss were better than expected performance goals. The structure has a larger safety reserve, and the performance stage of structure is IO.
