摘要
在钢屋架上施加预应力是解决工况超过标准图集时的有效方法。通过两个工程实例介绍了下弦带多点悬挂荷载的30m跨预应力钢屋架的设计和施工方法,对预应力筋布置形式、数量选择、承载力计算。
The design and construction methods of the prestressed roof truss spanning 30m with suspension loads are introduced herein. The main problems discussed here are the layouts of prestressing tendons,bearing capacity, deformation analysis and details of this kind of prestressed roof truss.
