摘　　要：广州某剧院高度为82.1 m,存在7项不规则项,裙房为1200座大剧场,塔楼主要为办公室,转换层位于六层楼面。运用结构概念设计思维,采用下部钢筋混凝土空腹桁架+上部带二次托柱转换的框架-剪力墙结构体系,叠层空腹桁架作为二次转换的安全储备,提高了结构的安全冗余度;进行了罕遇地震作用下的动力弹塑性分析及转换层楼板应力分析,通过提高底部加强区剪力墙配筋率、在转换构件中增设型钢、加强转换层楼板厚度及配筋等措施,可达到设计预期目标。Atheater in Guangzhou is 82.1 m high with 7 irregular items.The main functions of podium and tower are theater and office,respectively,and the transfer floor is located on the sixth floor.Using structural conceptual design thinking,the frame-shear wall structure system with lower reinforced concrete hollow truss and upper secondary conversion is adopted.The laminated open-web truss serves as a safety reserve for the secondary conversion,improving the safety redundancy of the structure.The dynamic elastic-plastic analysis under rare earthquake and stress analysis of the transfer floor slab were conducted.Through increasing the reinforcement ratio of shear wall in bottom strengthened area,adding steel to transfer members,and strengthening the thickness and reinforcementof transfer floor slab,the design targetcould be achieved.
