重庆施光南大剧院为一座容纳1 300人的大型剧院建筑,采用框架-剪力墙结构体系。本剧院建筑内部空旷,造成了若干楼层的楼板不连续,剧院与下侧的会议厅、宴会厅连为一个整体结构单元,建筑功能布局复杂。7.4m长悬挑看台、31.4m跨度剧场种植屋面、26m跨度会议厅和宴会厅是结构设计的难点,此外结构抗震超限、螺旋楼梯也是本工程的典型特点。通过多处应用预应力技术、采用多种软件进行分析、根据大震楼板应力结果指导薄弱板带的配筋设计、精心选择剪力墙的合理布置等综合手段,有效解决了上述技术难点,取得了良好的建筑使用效果和经济效益,相关设计施工经验可供类似工程参考。 Chongqing Shiguangnan Grand Theater is a large theater building accommodating 1,300 people. It adopts a frame-shear wall structure system. The interior of the theater building is open, resulting in the discontinuity of floors of several floors. The theater and the conference hall and banquet hall on the lower side are connected as an integral structural unit, and the layout of architectural functions is complicated. 7.4m long cantilevered stands, 31.4m span theater planting roof, 26m span conference hall and banquet hall is the structural design of the difficulties, in addition to structural seismic overrun, spiral staircase is also a typical feature of the project. Through the application of prestress technology in many places and the analysis by a variety of softwares, according to the stress results of large earthquake floor slab reinforcement design guidance, careful selection of the rational allocation of shear walls and other comprehensive means to effectively solve the technical difficulties and obtain A good use of the building and economic benefits, the relevant design and construction experience for similar projects for reference.
