摘要
大跨度钢结构场馆跨度大,结构受力复杂,卸载施工难度大。以福州海峡奥林匹克体育中心主体育场为例,对大跨度钢结构的卸载技术进行研究。采用砂箱卸载装置、分级不等值的卸载方法,通过施工卸载模拟计算,合理地分配分级卸载值,很好地解决了大跨度钢结构卸载施工难点。
Large-span steel structure stadium has the characteristic of complex force and difficult uninstall construction.Take the main stadium of Fuzhou Strait Olympic Sports Center for example to research the uninstall technology for largespan steel structure stadium. By using sandbox uninstall device,hierarchical un-equivalent uninstall and construction uninstall simulation calculation,the hierarchical uninstall value was allocated reasonably so that the problem of uninstall construction for large-span steel structure was solved efficiently.
