[摘要] 三河文化中心是集文化、体育、娱乐于一体的公建综合体。剧院结构体型复杂、结构空旷、楼板不连续、结构扭转效应大，通过准确的模拟计算，采取抗震措施和概念性设计加强来控制上述问题。剧院观众厅楼座的长悬挑、屋顶的大跨度预应力井字梁以及台口的预应力混凝土大梁设计是结构的设计难点，对此分别进行了介绍，为类似工程提供借鉴。

Abstract: Sanhe Culture Art Centre is a comprehensive pubic building of culture, sports and entertainment. It is a Hulding with many irregular characteristics such as structural hollowness, floor discontinuous, huge torsion effect. By accurate simulation, seisrmc measures and concept design were adopted to control the questions. The design of suspension beams of balcony in auditorium, long span prestressed cross-beams on proof and the big prestressed beam on stage were introduced respectively. The design experience will be good references for sinular project.
Keywords: frame-shear wall; prestressed concrete; long suspension; long-span steel roof truss
