摘　　要：天汉大剧院由北楼大剧院、南楼青少年活动中心和外围钢结构三部分组成,为典型的复杂连体双塔楼结构。以天汉大剧院为例,采用多种计算软件对多模型进行对比分析和包络设计,并针对关键构件和节点进行性能化设计。对于位置关系复杂的连接节点,采用BIM技术优化型钢梁柱节点钢筋与钢骨之间的连接关系。采用大震弹塑性分析软件ABAQUS研究不同角度罕遇地震作用下两个单体结构之间的水平位移差产生的结构内力对外围钢结构的影响。地基基础形式采用天然地基+筏板基础,大剧院主舞台台仓深度为17.5m,台仓范围采用筏板基础+抗拔桩,设计中合理控制相邻基础沉降差。结果表明:该项目结构选型及荷载布置合理,结构满足抗震性能要求,关键节点安全可靠,罕遇地震作用下两个单体结构之间的位移差产生的结构内力对钢结构构件影响较小。Tianhan Grand Theatre is composed of the north grand theatre,the south youth activity center and outer steel structure,which is a typical double-tower complex connected structure.Taking Tianhan Grand Theatre as an example,the multiple computational softwares were used to compare and analyze multiple models and envelope design,and performancebased design for key components and nodes was taken.For the connection joints with complicated positional relationship,BIM technology was used to optimize the connection relationship between the rebar and steel of the SRC beam-column joint.The large-seismic elastic-plastic analysis software ABAQUS was used to study the effect of the structural internal force generated by the horizontal displacement difference between the two single structures on the steel structure under the effect of rare earthquakes at different angles.The foundation adopts natural foundation+raft foundation,the depth of main stage understage of grand theatre reaches 17.5m,and the range of understage adopts raft foundation+uplift pile,and the settlement difference of foundations is reasonably controlled in the design.The results show that the structure selection and load arrangement of this project are reasonable,the structure meets the requirements of seismic performance,the key joints are safe and reliable,and the structural internal force generated by the displacement difference between two single structures under the action of rare earthquakes has a small impact on steel structural members.
