摘　　要：预应力张弦直梁结构由于其能够跨越较大跨度,在大型公共建筑中应用广泛。以南京国际博览中心二期平面张弦直梁钢屋盖结构工程为背景,对张拉施工分析时的零状态形态以及临时支撑胎架与钢梁摩擦、支座与钢埋件摩擦对张拉施工的影响进行研究。Prestressed string straight beam structure can stride across a large span,so it is widely used in large public buildings. Taking flat string steel roof structure of the Nanjing International Expo Center Phase II as the background,the zero-state shape of tension construction analysis and the influence on tension construction from the friction between the temporary supporting frames and the steel as well as bearing and the steels submerged were studied.
