DYNAMIC ANALYSIS OF BRIDGE-VEHICLE INTERA CTION FOR HIGHWAY BRIDGES -2 - APPLICATION TO THE SENNETERRE BRIDGE LOCATED IN QUEBEC

In this paper, an application of the algorithm for the dynamic analysi s of bridge-vehicles interaction that the authors developed in the pre ceeding paper is presented. The numerical results are compared to the results obtained from experimental tests of frequencies and mode shape s and from forced vibrations carried out on the Senneterre bridge loca ted in Quebec. The numerical model of the bridge is obtained by tridim ensional finite element modeling, using shell and beam elements, and t aking into account bridge-vehicles interaction and the road profile in a realistic way. The numerical vehicle model used in the province of Quebec is represented in a discrete form based on mechanical parameter s calibrated and adjusted according to experimental results. A paramet ric study was then carried out. The results of this study allow us to present some recommendations with regard to bridge resistance to dynam ic effects and the determination of a dynamic amplification factor bas ed on the specific loading conditions of the bridge.
