摘要
残奥会训练馆钢屋盖为大跨度钢结构网架,采用“逐条累积滑移”的施工技术。屋盖钢结构网架受安装路径效应影响较大,故采用SAP2000非线性施工模拟,按实际划分单元逐条安装钢结构网架模拟安装过程。研究表明,网架杆件应力集中在0~0.6,满足规范要求,屋盖钢结构网架最大位移值满足设计要求。
The steel roof of the Paralympic Training Hall is a large-span steel structure grid structure,which adopts the construction technology of progressive sliding.The roof steel structure grid is greatly affected by the installation path effect,so SAP2000 nonlinear construction simulation is adopted,and the steel structure grid is installed one by one according to the actual unit division to simulate the installation process.The research shows that the stress concentration of the grid members is 0~0.6,which meets the requirements of the code,and the maximum displacement of the roof steel structure grid meets the design requirements.
