变截面钢箱梁人行天桥的有限元分析

摘要

Using large-scale general finite element analysis software ABAQUS, this paper made detailed analysis on a variable cross-section steel box girder pedestrian bridge using shell elements, and accurately checked the intensity, deformation etc. of main beam.%应用大型通用有限元分析软件ABAQUS,采用壳单元对某变截面钢箱梁人行天桥进行了详细的模拟分析,准确地验算了主梁的强度、变形等,结果表明该分析方法效果较好,可为今后类似工程提供指导。
