威海国际商品交易中心斜拉索工程施工

Stayed-cable Construction of Weihai International Trading Center

威海国际商品交易中心总体分中区、南区和北区3部分,其中心屋架采用"桅杆+钢桁架+斜拉索"结构体系,其中斜拉索的安装及张拉施工是施工中的重点和难点。介绍了斜拉索结构体系的张拉分析、结构安装和张拉施工工艺。根据仿真分析结果提出了相应的技术措施和作业方法,使得施工顺利完成,各方反映良好。

Weihai International Trading Center is composed of center area, north area and south area. Mast, steel truss and stayed-cable structure system is used in central roof truss. Installation and tension of the stayed-cable are key points and difficulties during construction. Tension analysis, structure installation and tension technology of stayed-cable system are introduced in this paper. According to simulation results, corresponding technical measures and construction methods are proposed. The project is smoothly finished, and reflects well.
