摘　　要：利用ANSYS软件对装配式钢桁架桥桥跨结构进行模态分析,得到了桥跨结构的损伤现象和易损伤位置,进行了实装实验,验证了仿真分析的正确性。We performed the modal analysis of the cross-structure of assembled steel truss bridge with ANSYS, and the damage phenomenon and damage position of bridge cross-structure were obtained. After that, there was an actual experiment, and the correctness of simulation analysis was verified.

关 键 词：模态分析 装配式 桥跨结构 故障诊断
