［摘要］介绍了泰州国际博览中心二期结构的设计思路。本工程空间造型复杂，由大跨度的型钢混凝土框架结构、90m跨带两道斜拉索的箱形实腹钢梁屋面及外蒙皮钢结构组成，形成彼此既相互独立又相互支撑的系统。带斜拉索的箱形实腹钢梁屋面造型新颖，很好实现了建筑的空间构想。采用抗震性能化设计，对关键构件抗震性能进行提高，按整装模型采用多程序进行受力分析计算，对超长钢筋混凝土结构进行了温度及收缩应力分析，结果表明建筑安全可靠。

Abstract:Structural design concept of  Taizhou International Expo Center on the second phase was introduced. The project is a spatial structure with complicated facades and is composed of long-span steel reinforced concrete frame structure, box shaped  solid web steel beam roof with two stay cables with span of 90 meters and outer skin steel structure. Thus the system which is independent and supported mutually is formed. A new type of box shaped solid web steel beam roof with stay cables was applied to meet the requirements of  architectural space concept. With the concept of performance-based seismic design, anti-seismic property of key component was improved, stress analysis and calculation was completed based on multi process according to the integrated model, temperature and shrinkage stress of the super long reinforced concrete structure was analyzed, and the results show that structure is safe and reliable.

Keywords:Taizhou International Expo Center; stay cable; box shaped solid web steel beam; steel structure; spatial structure; performance-based seismic design
