【提要】 大剧院结构具有体型复杂、内部空旷、跨度大等特点。以福建大剧院和大庆大剧院为例，总结出大剧院的抗侧力体系应选择框架剪力墙结构，不同使用功能的空间应采用不同的楼板布置方法。通常设置后浇带和加强带解决大跨、超长问题，在计算中应采用与实际结构做法相近的计算条件。风荷载的取值应该根据实际情况选用。屋盖与下部结构的连接应采用特殊的支座形式。根据不同的场地，选取合适的基础形式。

Abstract:The theatre structures characterize complex shape,hollow inside and large span. Using the Fujian theatre and Daqing theatre as examples,it is concluded that the frame shear wall structure is adopted,and the relative floor distribution should base on the different function of the rooms.The postpouring drip and strengthening drip are used to solve the large span and super long problems.The calculation condition close to the practical design should be adopted in structural computation.The special bearings that connect the roof and the structure below are used,and the suitable foundation is chosen according to different ground condition.
