Stress Performance Theory and Experimental Comparison Analysis on Spatial Steel Pipe Truss Roof

Abstract:

A newly built train station housing cover using a parasol unit structure,main structure component is bidirectional cantilever stell truss,chord rod is large size welding thin wall box section,canopy adopt large span steel truss.Because the span of the structure is large,the structure is strange,the process of the construction is complex, plus the period is long and difficult,so there are uncertain factors in the process. Therefore,the process of construction mechanical characteristics and design states may be different.It is necessary to conduct stress performance monitoring in the construction process.This paper introduces test condition of train station roof structure.At the same time,the installation process of the stell roof system is simulated and analyzed with MIDAS in this paper.By the analysis and comparison of the test value and the theoretical analysis of the scene,there are some rule of deform and stress in the process of construction and points out some problems needing attention in the construction period.
