摘　　要：利用SAP84计算程序和根据设计规范手算相结合 ,对 15 0m钢混结合梁施工过程中开口截面钢梁的稳定性进行分析比较 ,介绍建模及计算过程 ;同时根据计算结果 ,揭示结构的薄弱环节 。An analysis was made of the stability of open section steel girder during construction of 1-50m steel-concrete composite girder by means of combined computation of SAP84 and manual computation. The process of model establishment and calculation was introduced. Computation result indicated the weak point of the structure, and was used to verify the effect of structure stabilizing measures.
