［摘要］介紹了泰州國際博覽中心二期結構的設計思路。本工程空間造型復雜，由大跨度的型鋼混凝土框架結構、90m跨帶兩道斜拉索的箱形實腹鋼梁屋面及外蒙皮鋼結構組成，形成彼此既相互獨立又相互支撐的系統(tǒng)。帶斜拉索的箱形實腹鋼梁屋面造型新穎，很好實現(xiàn)了建筑的空間構想。采用抗震性能化設計，對關鍵構件抗震性能進行提高，按整裝模型采用多程序進行受力分析計算，對超長鋼筋混凝土結構進行了溫度及收縮應力分析，結果表明建筑安全可靠。
［關鍵詞］泰州國際博覽中心； 斜拉索； 箱形實腹鋼梁； 鋼結構； 空間結構； 抗震性能化設計

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
