摘要
厦门国际会展中心三期部分屋盖结构体系采用大跨度张弦梁结构,跨度最大达97m,单榀重量达60t。施工中采用"分段预拼装、两榀同时预应力张拉"的施工方案。同时利用非线性有限元法分析,采用迭代法,模拟预应力张拉过程张弦梁的状态,可为同类工程提供一定的借鉴经验。
The roof structure system of Xiamen International Exhibition Center is used large-span beam string structure,the span up to 97 meters,single specimens of weight up to 60 tons. Construction of a ＂ pre-assembled segments,while two specimens prestressed tension,＂ the construction program. At the same time the use of nonlinear finite element analysis,using an iterative method to simulate the process of prestressed beam string tension state,the experience can provide a reference for similar projects.
