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

  • 摘要: 基于应用影响线函数由监测效应反演荷载的理论分析,提出了通过构造监测截面监测力学量影响线函数,建立监测力学量与桥上车辆荷载的关系式,应用监测信息反演过桥车辆荷载的荷载识别方法. 实例结果表明该方法能有效地识别桥上车辆荷载载重.

     

    Abstract: 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.
