广西体育中心游泳跳水馆钢屋盖采用空间管桁架与单层网壳组合结构。空间管桁架为主受力构件,由横向八榀落于地面基础的空间管桁架与纵向四榀落于两端墩台的空间管桁架组成,作为支撑的单层网壳可增加钢屋盖整体刚度并直接承担相应部分屋面荷载。主要介绍了该工程钢屋盖的结构选型并对同时考虑几何和材料非线性的稳定性进行分析。
Guangxi Sports Center Swimming Diving Museum Steel roof truss space truss with single-layer reticulated shell structure. The space truss is the main force component. The space truss consists of a space tube truss which falls horizontally on the ground and a space tube truss which falls on the pier at both ends in the longitudinal direction. The single-layer reticulated shell as a support can increase the whole steel roof Stiffness and directly bear the corresponding part of the roof load. This paper mainly introduces the structure selection of the steel roof of the project and analyzes the stability of both the geometry and the material nonlinearity.
