Abstract: In order to identify moving loads on a bridge, the vehicle/bridge system is modeled as a simply supported beam subjected moving loads. The equation of motion of bridge is set up by finite element method. Based on the measured bridge responses, generalized orthogonal function approach and model superposition principle are used to obtain the derivatives of the modal responses, and the regularization technique is used to obtain the stable identified results. Simulation results and laboratory tests show that the method is effective and accurate to identify the moving loads on the bridge.
