摘　　要：以上海国际舞蹈中心大剧院为背景工程,在抗震分析与设计中,采用多种计算软件对抗震结构进行小震、中震、大震的计算,分析了结构不规则对整体结构抗震性能的影响,重点分析研究了关键构件斜框架和核心剪力墙的抗震性能。针对特殊部位进行专题结构分析,比如旋转楼梯借助有限元软件MIDAS/Gen和ABAQUS分析计算,为充分利用梯段板宽度,创新采用箱梁的结构形式替代传统梁的结构形式,降低了结构层的截面高度,达到了良好的效果。上海国际舞蹈中心大剧院结构设计既要保证结构的安全性,也兼顾了建筑的功能性和室内的整体效果,具有一定的技术创新,为剧院建筑的结构设计提供了一定的参考。Taking the Grand Theater of Shanghai International Dance Center as the background project,in the seismic analysis and design,a variety of calculation software are used to calculate the small,medium and large earthquakes of the seismic structure,analyze the influence of structural irregularity on the seismic performance of the overall structure,and focus on the seismic performance of the key components,inclined frame and core shear wall.Special structural analysis is carried out for special parts,such as rotating stairs.With the help of finite element software MIDAS/Gen and ABAQUS,in order to make full use of the ladder slab width,the structural form of box girder is innovated to replace the structural form of traditional beam,which reduces the section height of structural layer and achieves good results.The structural design of the Grand Theater of Shanghai International Dance Center should not only ensure the safety of the structure,but also consider the functionality of the building and the overall indoor effect,which has certain technological innovation and provides a certain reference for the structural design of the theater building.
