Basic Consideration of Weigh-In-Motion using Control Theory

Abstract

In bridges, vibrations caused by the traffic loading are responsible for advancing the fatigue damage of the bridge. To continually grasp the vehicle weight of the traffic load that generates vibrations are very important in the maintenance of bridge. Currently, as a system for indirectly measuring the axle load of the vehicle traffic on the bridges, there is a BWIM (Bridge Weigh-In-Motion) to implement the load measurement of the traveling vehicle from the analysis of the strain response. This study proposed a method to identify the load effect and the vehicle weight to the beams of the moving load by using the control theory.
