摘　　要：最近,对老旧建筑的改造是城市发展的重要工作,而如何实现安全可靠的改造过程是关键问题。本文基于ANSYS有限元软件,运用生死单元法对某体育馆钢屋架的杆件拆除施工过程进行数值模拟分析。基于这个工程案例,提出一种空间结构屋盖施工过程分析方法,分析杆件的强度验算、杆件的稳定性验算和结构挠度验算。结果表明:空间结构屋盖施工过程分析方法能准确分析结构的受力状态,合理预测施工过程中结构的内力变化,进而评估施工方案的安全性,为改造工程的施工过程分析提供了有效手段,也为类似的既有建筑改造工程提供了借鉴和参考。Recently,the renovation of old buildings is an important work of urban development.How to realize the safe and reliable transformation process is the key problem.In this paper,based on ANSYS finite element software,the birth and death element method was used to simulate the construction process of steel truss roof of Xinxing County gymnasium.Based on this engineering case,a method for analyzing the construction process of spatial roof structures was proposed.The results show that the construction process analysis method of spatial roof structure can accurately analyze the stress state of structures,reasonably predict the internal force change during the construction process,and then evaluate the safety of construction scheme.This analysis case provided a reference for similar reconstruction project of existing building.
