［摘要］嵊泗海洋文化中心是嵊泗縣“十一五”期間的重點項目之一，層2看臺采用大跨度鋼結(jié)構(gòu)曲梁結(jié)構(gòu)形式。著重分析了大跨度曲梁節(jié)點設(shè)計及先約束后放松支座施工技術(shù)，利用MIDAS軟件建模模擬了大跨度曲梁看臺的工作性狀。鑒于主體結(jié)構(gòu)已施工，分區(qū)吊裝、現(xiàn)場拼接給結(jié)構(gòu)設(shè)計造成了更多困難。通過該項目的介紹可為此類大跨度鋼結(jié)構(gòu)的設(shè)計、施工提供有益經(jīng)驗。

Abstract:Shengsi Ocean Cultural Center is the important project of Shengsi County during “the 11th Five-year Plan”, which adopts large span steel structure system. The working condition of large span curved beams is analyzed by MIDAS. The methods of large span curved beam about detailed design and slackening after restraint to belts are discussed. Due to the main structure is almost completed, suspension setting and splice in subzone put forward high requirements to structure design. The experience deduced could be useful in other similar large span projects.
Keywords:large span curved beam; slackening after restraint; FEM
