摘　　要：江宁体育馆屋盖采用拉索悬吊交叉桁架预应力钢结构体系,其拉索张拉采用部分调整索长、部分张拉的方案,仅通过张拉部分拉索而在其他拉索中也建立了设计所需的预张力,大大减少了设备用量和张拉次数,提高了张拉效率。The gymnasium roof adopts pre-stressed cable-suspended cross steel truss structure,and tensile cables are tensioned partly by adjusting cable length and partly by tensioning. Though only some tensile cables are tensioned, designed pretension is also established in other tensile cables. Less equipment is therefore used; number of tensioning reduced greatly; and tensioning efficiency improved.
