Bridge Weigh-in-Motion by Strain Measurement of Transverse Stiffeners

Good bridge maintenance schemes rely on knowing how truck loads act upon the bridge, and weigh-in-motion techniques are increasingly in demand as bridges in Japan age rapidly and require economical and practical bridge maintenance. Bridge weigh-in-motion (B-WIM) is based on the deformation of a bridge and has gotten much attention in Japanese bridge engineering due to its lower cost in comparison to conventional pavement scales. B-WIM involves primarily measuring the strain of the main girder, but also measuring the strains of transverse stiffeners can provide useful supplemental information. In this study, the authors conduct B-WIM using only the strains of transverse stiffeners, employing an integrated method called BWIM-IT. They conclude that careful selection of transverse stiffeners allow for the accurate estimation of truck loads using only those strains, and they find their method to be simple and cost effective.
