摘要: 根据铰缝在装配式板桥传递荷载的作用,通过数值计算方法模拟了装配式板桥在铰缝损伤后的瞬态动力学 响应,比较分析了不同损伤程度、不同动荷载加载位置下各板跨中加速度幅值,提出利用多次冲击实验下各板加速 度幅值比之差值作为铰缝损伤的评定依据的识别方法,并分析了这种方法的可行性。

Abstract: Hinged joint is the essential component of prefabricated slab bridge which transfers load from one slab to other slabs. Based on this role,many transient dynamic analyses about prefabricated slab bridge models with several extent damaged of hinged joint and different position of dynamic load are simulated by FEM method numerically. The transient acceleration amplitudes of every slab are analyzed and compared. It is suggested that the difference values of acceleration amplitude ratios of several impact tests could be used to identify the damage extent and position of hinged joint. The feasibility and practicability of this method is demonstrated.

Key words: prefabricated slab bridge, hinged joint, transient dynamic, damage identification
