［摘要］苏州浒墅关文体中心主体部分为钢筋混凝土框架带局部支撑的双塔结构，屋面为大跨钢屋面，双塔间通过南北曲面幕墙及中庭玻璃顶钢网格连接，空间连接复杂。针对主体结构存在的各种不规则类型，在设计中合理布置框架斜撑、调整结构各部分梁柱构件截面以减弱结构的不规则程度，并对结构关键构件进行性能分析，对大跨钢屋面进行了稳定分析，特别优化了中庭玻璃顶钢网格及曲面幕墙结构与主体结构间的连接。分析结果表明，相关设计满足结构抗震性能及安全性要求。

Abstract:The main part of  Suzhou Xushuguan Cultural and Sports Center is a reinforced concrete frame with  partially braced tow towers, and the roof is a large-span steel roof. The two towers are connected by a north-south curved curtain wall and an atrium glass top steel grid, and the space connection is complicated. Aiming at the various irregular types of the main structure, the frame braces were reasonably arranged, and the cross-section of the beam-column members of each part of the structure was adjusted to weaken the irregularity of the structure. The performance analysis of the key components of the structure was carried out, and the stable analysis of large-span steel roof was carried out. The connection between the atrium glass top steel grid,  the curved curtain wall structure and the main structure was specially optimized. The analysis results show that the relevant design meets the seismic and safety requirements of the structure.

Keywords:irregular structure; partial braced reinforced concrete frame structure; seismic performance design; large-span steel structure
