[CS2-23] Experimental Analysis on Moving Vehicle Force Identification from Bridge Responses Using an Extended Kalman Filter
Keywords:Bridge monitoring, Bridge weigh-in-motion, Moving load identification, Extended Kalman filter
A vehicle passing across a bridge leads to bridge vibration. The effects from passing vehicle’s load on bridge are divided into static effect and dynamic effect. The static effect usually indicates the pseudo-static responses of the bridge caused by the vehicle gross weight while the dynamic effect is related with factors including vehicle dynamic properties and bridge pavement roughness. In this paper, a method is proposed to identify vehicle’s dynamic load time history and its transverse position only from responses recorded by portable accelerometers using an extended Kalman filter.
