INVERSION OF VEHICLE LOAD ON BRIDGE FROM THE MONITORING INFORMATION BASED ON THE THEORY OF INFLUENTIAL LINE

Based on the inversion from the response to load,an identification method of vehicle load on a bridge by usingmonitoring information is presented in this paper. In this method, the relation of themonitored force indices and the vehicle load on the bridge is established byconstructing the influential functions of the indices on the measurementsection. The actual example indicates that themethod can fairly and accurately identify the weight of the vehicleacross the bridge.
