［摘要］苏州大剧院建筑空间关系复杂，由IMAX影院与大剧院主体两个结构单元组成。IMAX影院为钢框架-中心支撑结构，大剧院主体为钢框架-剪力墙结构。通过对IMAX影院和大剧院主体结构方案进行深化分析，明确超限类别及性能目标，并确定异形大跨飘带结构对大剧院结构的影响。针对结构体系中的重点、难点采用相应的计算分析方法和加强措施，保证了结构的安全及良好的抗震性能。

Abstract:Suzhou Grand Theater has complex spatial relationships and comprises two structure unites of the IMAX theater and the opera house. The IMAX theater is steel frame-central sustained structure, and the opera house is steel frame-shear wall structure. By deepening the structural concept analysis of the IMAX theater and the opera house, the out-of-codes classification and the seismic performance objective were determined. The influences of the large span special ribbon-shaped structures on the opera house were defined. According to the key points and difficulties of the structural systems, the corresponding calculation methods and enhancing measurements were adopted. All of these ensure that the structures are safe and have good seismic performances.

Keywords:Suzhou Grand Theater； complicated spatial structure; steel frame\|central sustained; steel frame-shear wall; large span special ribbon-shaped structure
