摘要(Abstract):

以建成的上海凯迪拉克体验中心复杂钢结构为例,采用基于性能的抗震设计理论和方法,对结构进行抗震性能设计分析。采用YJK和SAP2000软件进行多遇地震作用下的弹性分析以及设防地震作用下的弹性和不屈服分析,采用PERFORM-3D软件进行罕遇地震作用下的弹塑性时程分析,从而验证结构抗震性能指标是否满足规范要求。通过分析罕遇地震作用下的塑性发展情况,找出结构的薄弱部位和构件,根据分析结果提出加强措施以保证结构具有良好的抗震性能。
Taking the complex steel structure of the Shanghai Cadillac Exhibition Center an example, the performancebased seismic design theory and method are used to analyze the seismic performance of the structure. YJK and SAP2000 software were used to conduct the elastic analysis under frequent earthquake action, elastic and non-yielding analysis under fortification earthquake action. PERFORM-3D software was used for elastic-plastic time history analysis under rare earthquake, so as to verify whether the seismic performance index of the structure met the requirements of the code. By analyzing the plastic development under rare earthquake, the weak parts and components of the structure were identified. According to the analysis results, strengthening measures were proposed to ensure the structure has good seismic performance.
