摘　　要：国际广场结构主体高度200.200 m,为钢筋混凝土框架—核心筒结构体系;结构高度B类,结构存在软弱层而竖向不规则。在弹性状态下,运用SATWE对主体结构基本参数进行了计算,重点介绍了结构抗震能力的设计,采用PKPM的EPDA&PUSH模块进行push-over推覆分析和罕遇地震下的动力弹塑性时程分析。弹性分析显示结构各项力学指标比较满意,整体计算分析满足规范要求。通过弹塑性时程分析,得出结构具有良好的抵抗地震的能力,能满足预定抵抗地震的要求,并采取技术措施以满足超限审查的要求。The main body height of an international square structure is 200.200 m, which is a concrete frame- core tube structure system; It is a hight of class B structure, which has al weak layer. It is also vertical irregu- lar. SATWE was used to calculate elastic basic mechanics performance of the main structure, and compare the calculation results with the results of PMSAP module. The seismic behavior of the structure was explored. Under severe earthquake, the pushover analysis and dynamic elastic-plastic time history analysis were implemented though PKPM EPDA＆PUSH. Elastic analysis indicates that the engineering calculation results are good, and the overall results meet the specification requirements. Elastic-plastic time history analysis shows that the structure has good seismic performance and can meet the predetermined seismic performance goals. Besides, some technology measures were adopted to strengthen the weak parts.
