摘要
针对分阶段提升施工方法在管桁架安装过程中结构的受力性能发生变化的问题,以大跨度钢管桁架屋盖为研究对象,对钢管桁架整体提升施工过程力学性能进行研究分析.运用有限元分析软件SAP2000,完成了对提升阶段各工况下的应力应变分析,分析了整体提升施工中的应力应变的监测情况.
Abstract
The phased lifting construction method has many advantages in the installation process of tubular trusses.However,during the implementation of this construction method,the stress performance of the structure will change.Therefore,it is of great significance to analyze the stress performance of the phased lifting construction process of tubular trusses to ensure construction safety and structural stability.This article takes the large-span steel tubular truss roof as the research object,and studies and analyzes the mechanical properties of the whole lifting construction process of steel tubular trusses.Using finite element analysis software SAP2000,the stress and strain analysis under various working conditions during the lifting stage is completed,and the monitoring situation of stress and strain during the whole lifting construction is analyzed.
