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。
Shengsi Marine Culture Center is one of the key projects in Shengsi County during the “11th Five-Year Plan” period. The grandstands of Grade 2 grandstands adopt the structure of large-span steel curved structures. The design of the large-span curved beam node and the construction technology of restraint and post-relaxation support are emphatically analyzed, and the working characteristics of the large-span curved beam observatory are simulated by using MIDAS software. In view of the main structure has been construction, zoning hoisting, on-site splicing structural design caused more difficulties. The introduction of this project can provide useful experience for the design and construction of such large-span steel structures.
