摘要
万州体育中心主体育场下部看台为钢筋混凝土结构,西区覆盖拱形屋盖。屋盖结构为拱跨约250m的超限大跨度巨拱结构,由钢管桁架组成。对大跨度屋盖结构布置及结构设计进行了阐述,并采用SAP2000软件对其进行了整体计算、施工模拟分析和防连续倒塌分析;采用ANSYS软件对结构进行了整体稳定性分析,并对典型节点进行了有限元分析。计算结果均满足结构安全性要求。
The lower stands for Wanzhou Sports Center Stadium adopts the reinforced concrete structural system with arch roof in the western zone. The roof structure is an out-of-code large-span super arch structure with the span of about 250 m,composed of steel pipe trusses. The layout and design of the large-span roof structure were described. The software of SAP2000 was used to carry out the overall calculation,construction simulation analysis and progressive collapse analysis.The overall stability analysis of the structure was carried out using ANSYS software. The finite element analysis was carried out on typical joints. All the calculated results meet the structural safety requirements.
