大跨环状空间钢桁架结构施工仿真与监测
Construction Simulation and Monitoring of Large-Span Circular Spatial Steel Truss Structure
摘要
Abstract
To investigate the mechanical characteristics of large-span steel truss structures during construction,a large-span circular spatial steel truss structure was selected as the research object.Based on Midas Gen software,the hoisting construction process of the steel structure was simulated,and a stress monitoring scheme was formulated according to the finite element analysis results.The measured values at critical locations were compared with the finite element results.The results showed that the structural stresses under various working conditions met the limit requirements,and the steel remained in the elastic working stage.The measured stress increments were generally consistent with the simulated values.The stress distribution pattern during hoisting construction was obtained,and the reliability of finite element analysis in the elastic stage was demonstrated,which can provide a reference for the construction of similar projects.关键词
