摘　　要：斜拉网架是一种新颖的、由“刚性”和“柔性”基本构件组合而成的具有良好性能的杂交空间结构体系。本文以某体育馆斜拉折板型网架为工程背景,对这种斜拉结构进行了整体分析,采用张力松弛法计算得到索的施工控制应力。结果表明张力松弛法是计算斜拉网架的有效方法。Cable-stayed space truss is a new hybridized spatial structure with good performance,which is made up of rigid and flexible basic compenents. This text made a whole analysis to the cable-stayed space truss combining a practical engineering of a gymnasium. Moreover, the tensile force slacken analysis method was used to obtain the control stress of construction. The result indicated the tensile force slacken analysis method was effective in calculating the cable-stayed space truss.
