摘　　要：深圳湾创新科技中心为超高层连体结构,不设加强层。选用ABAQUS和Perform-3D软件,基于不同力学模型和分析假定,对结构进行了大震下的弹塑性时程分析;接着对比分析了结构在地震作用下整体指标、层间位移角、层间剪力、顶点位移时程、基底剪力时程、能量耗散和结构塑性损伤情况。结果表明,复杂连体结构采用多种软件进行动力弹塑性分析是必要的。鉴于此,提供了Perform-3D和ABAQUS两种软件的弹塑性分析方法及思路。Shenzhen Bay Innovation Science and Technology Center is a super high-rise connected structure without strengthening layer.Based on different mechanical models and analysis assumptions,the elastic-plastic time history analysis of the structure under large earthquakes was carried out by using ABAQUS and Perform-3D software.Then,the overall index,inter-story displacement angle,inter-story shear force,vertex displacement time history,base shear time history,energy dissipation and structural plastic damage of the structure under earthquake were compared and analyzed.The results show that it is necessary to use a variety of softwares for dynamic elastic-plastic analysis of complex connected structures.In view of this,the elastic-plastic analysis methods and ideas of Perform-3D and ABAQUS software were provided.
