摘要
根据可拼装式三维钢桁桥的结构特点 ,可拼装式钢桁桥的拼装单元可被肢解成子结构。在空间杆系有限元法的基础上 ,利用模态综合技术对可拼装式钢桁桥进行振动分析。通过结构振动试验 。
The 3D prefabricated truss steel bridge can be divided into substructures as assembly cells by using its structural characteristic properly.The mode synthesis technique which is based on 3D girder FEM is applied to analyze vibration of the bridge.The experimental research on the bridge is considered in order to demonstrate the validity of theoretical analysis.
