摘要
针对大跨度钢屋架整体滑移方案,以五棵松体育馆为工程背景,应用ANSYS有限元软件对钢结构屋盖主桁架的整体滑移过程进行了动态模拟跟踪分析,得到滑移过程中不同阶段应力及变形的变化范围,以确定最佳安装方案。分析表明,在保证合理措施的条件下,此滑移方案是可行的。
It is analyzed the integral slippage scheme of the large-span steel roof truss for Wukesong Gymnasium. Based on the ANSYS finite element program, it is monitored and traced that the continuous checks of the modulation of deformation and stress distribution of the main truss during the various phases of slipping process, thus, ascertaining the optimal installation scheme, The results prove that the optimal scheme is feasible on the condition of reasonable measures.
