摘 要: 本文按照我国的有关规范(特别是荷载取值和材料强度取值)和风洞试验结果所提供的数据,对广州国际会议展览中心展览大厅钢屋盖126.6m跨度的预应力张弦立体桁架钢结构进行计算与分析.文中主要对矢跨比、拉索数量、预应力度等三个参数进行了比较分析. Based on the Chinese design standards and the wind tunnel test results, this paper describes the design and analysis of the prestressed spatial truss string structure with a long span of 126.6m, which is the steel roof structure of the exhibition hall at Guangzhou International Convention & Exhibition Center. Comparison analyses are conducted for three parameters including the risetospan ratio, the number of cables and the prestressing magnitude.
