Abstract

An interactive behavior between a bridge and a vehicle periodically stimulated by road roughness was observed through systematic testing. Periodic roughness was simulated by using wooden planks placed at various distances across the road. The vehicles, two 7.5-ton trucks, were run across the bridge with varying loads and at varying speeds. The test bridge was a two-span prestressed concrete pedestrian structure on which many sensors were placed. A complete model was developed on the basis of separate components, including excitation, vehicle, and bridge. These components were linked in the final calculating step. Particular attention was paid to determining the stiffness of the superstructure.
