 Abstract:

To achieve the dynamic response of the arch bridge as the vertically curved bridge widely applied to the main structure of the bridge subjected to dynamic loads, the simulative methods based on engineering software have been used more popular than the analytical methods or finite element methods because of those complications. It is difficult to propose a general solution for analyzing dynamic response of the arch bridge due to different dynamic loads applied widely and easily in the design practice. Hence, this paper proposes the simplest model for the dynamic response of a multi-span arch bridge subjected to moving vehicle. The arch bridge modeled as a multi-span uniform arch beam resting on elastic spring supports is disjointed based on finite element method. The moving vehicle is described by two masses corresponding to car body and wheel. And then, the governing equation of motion of the bridge-vehicle interaction is derived based on dynamic balance principle and solved by Newmark method in the time domain. The accuracy of the algorithm is verified by comparing the numerical results with the other numerical results in the literature. Therefore, the influence of characteristic parameters of the multi-span arch bridge-vehicle interaction such as vertical curved of an arch bridge, the elastic stiffness of the support and the property parameters of the moving vehicle on the dynamic response of the system structure are investigated detail. The numerical results showed that those parameters affect significantly on the dynamic response of the multi-span arch bridge-vehicle interaction. It can be also seen that this study has meaningful practice in the problems of design and analysis response of the arch bridge due to moving traffic load.
