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 Perform-3D software and inputting three seismic waves, the dynamic elasto-plastic analysis of the engineering example was carried out. The seismic elastic properties of the engineering example were evaluated by taking the elastic-plastic deformation quantitative index of ASCE 41 as an acceptable criterion. The results show that in rare earthquakes The lower stiffness of the lower structure is reduced to a limited extent, and the structure is in a weakly nonlinear state. The performance indexes such as the drift angle of the layers meet the requirements of the code and meet the design requirements of “strong columns and weak beams”. The components such as shear walls and frame beams Better than expected performance objectives, the structure is in operational control performance stage, have more safety reserves.
