摘　　要：以杭州市某国道的整治工程为背景,利用大型有限元软件ABAQUS对其上的一联钢箱梁桥的中横梁进行了仿真分析。结果表明减小横隔板与中横梁的距离,可以有效地减小中横梁上剪应力的大小;取消人孔,可以有效地改善中横梁上剪应力的分布。文中分析结果可为以后钢箱梁处中横梁的设计提供可靠参考。Taking a national highway in Hangzhou city as the engineering case,this paper proposed a simulation of the middle cross beam in the steel-box beam by the finite element analysis of ABAQUS.The results show that the diaphragm distance reduction can decrease the shear stress of the middle cross beam effectively.Additionally,the shear stress distribution of the middle cross beam without manholes will be improved compared to that with manholes.Finally,these results may offer reference for the design of the middle cross beam in the steel-box beam.
