［摘要］嵊泗海洋文化中心是嵊泗县“十一五”期间的重点项目之一，层2看台采用大跨度钢结构曲梁结构形式。着重分析了大跨度曲梁节点设计及先约束后放松支座施工技术，利用MIDAS软件建模模拟了大跨度曲梁看台的工作性状。鉴于主体结构已施工，分区吊装、现场拼接给结构设计造成了更多困难。通过该项目的介绍可为此类大跨度钢结构的设计、施工提供有益经验。

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
