摘　　要：淮安大剧院位于7度抗震设防区,设有1 230个座席.建筑整体由上、下两个不同心的空间椭圆组成,建筑总高度为19.425～28.074 m.主体结构在观众厅周边及舞台平面转角部位适当布置剪力墙形成钢筋混凝土框架-剪力墙结构.根据建筑体型需要,入口门厅采用斜柱钢结构体系,下端采用型钢混凝土柱与之过渡,并与下部混凝土构件可靠连接,屋面支座与主体结构铰接,在增大钢结构整体刚度和稳定性同时减小水平力作用下对混凝土结构的影响.建筑周边设置单向预应力拉索玻璃幕墙,最大拉索长度18m,单索拉力较大达到590 kN,前厅采用外挑钢梁及自平衡钢立柱、后台及侧台周边采用钢筋混凝土外挑桁架作为拉索幕墙支座.经计算分析,设计满足相关规范要求.Huaian theater is 1 230 seats theater which is in the district of intensity of seven degree. The building is composed by two non concentric spatial ellipse, the height of the building is 19. 425-28. 074 m. Some shear walls are arranged around the auditorium and stage to form a reinforced concrete frame-shear wall structure. According to the needs of the building shape, the entrance hall is composed By declining steel columns, the lower end of the column connected with steel reinforced concrete column, the upper end of the bearing is hinged with the roof, these can increase the whole stiffness and stability of the steel structure while reducing the level of force on the concrete structure . Around the building use prestressed cable glass curtain wall, the longest cable is 18 m and the tension force reached 590 kN. The cable holders in antechamber are steel beams and self-balancing steel columns and in the background are reinforced concrete trusses.
