Abstract
Bridge based weigh-in-motion system A weigh-in-motion system for sensing dynamic strain variations in a bridge, comprising a plurality of strain sensors and a plurality of fixtures arranged as a plurality of sensing nodes; wherein each sensing node comprises: a first one of the fixtures comprising a first connector part and a first base attachable to a first location on the bridge; a second one of the fixtures comprising a second connector part and a second base attachable to a second location on the bridge; wherein the first location and the second location are separated by a distance B and define therebetween a measurement section; and one of the strain sensors that spans between and is fixed to the first and second connector parts by rigid fixings, separated by a distance A and defining therebetween a sensing section, so as to thereby form a spring connection between the first and second connector parts, the spring connection being extended or compressed to enable the strain sensor to provide an output signal dependent on the relative position of the first and second connector parts.
