摘　　要：芜湖苏宁广场建筑功能多造型复杂,结构平面及竖向具有多项不规则,根据新高规,采用基于性能的抗震设计,针对不同构件,根据其重要性制定了不同的预期性能目标。计算采用多种软件和计算方法,分析了结构在不同地震水准作用下的弹性、弹塑性响应,同时采用了多种构造加强措施,使结构具有良好的抗震性能与延性,能够实现设计性能目标。Wuhu Suning Plaza is a construction project which has multiple functions and complex modeling,in its horizontal plane and vertical direction,there are numbers of irregular forms.According to the new Chinese standard,the seismic design has been adopted based on the use of the building＇s performance In view of different structural components,depends on their importance,different performance objectives have been made.In this project,varieties of software and calculation methods have been used to analyze the elastic and elastoplastic performance of structures when they are in different seismic standards.Meanwhile,multiple tectonic confinement technologies have been used in this construction progress,so that the structure systems will have a good seismic performance and ductility,then it can help to achieve the design performance objectives.
