（广西华蓝设计集团有限公司，南宁 530011）[摘要] 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。[关键词] 空间管桁架; 单层网壳; 稳定分析; 几何非线性; 材料非线性中图分类号：TU393.3 文献标识码：A 文章编号：1002-848X(2013)S2-0453-04Stability of the steel roof system of Aquatic Center of Guangxi Sports CenterLiu Hong, Jing Xiangxiao, Hu Gang（Guangxi Hualan Design & Consulting Group, Nanning 530011, China）Abstract: The steel roof of Aquatic Center of Guangxi Sports Center Space adopts spatial tubular truss structural system with single layered lattice shell. As the main supporting structure, space tubular truss consist of eight transverse truss units that go straight down to the ground and four longitudinal truss units supported on the piers at two ends. Single layered lattice shell serves as bracing members to increase the overall rigidity of steel roof and directly undertakes loadings from the roof. Structural system selection and nonlinear stability analysis of the roof considering both geometric and material nonlinearity are introduced.Keywords: spatial tubular truss; single layered lattice shell; stability analysis; geometric nonlinearity; material nonlinearity
