“…In the event of a sudden loss of a load-carrying element, a bridge immediately experiences an alteration of load paths. The continued stability and performance of the bridge can thus be broadly attributed to its capacity to find alternative load paths [5]. When the structure is not able to find alternative load paths, progressive collapse can occur.…”

“…The BWIM technique first obtains the strain time course at the measurement point by calibrating the structural impact line using a standard vehicle passing over the bridge. The strain response time course under any traffic condition is then obtained based on this information, and the number of vehicles, vehicle type, and vehicle weight are inferred using certain principles and algorithms (Hitchcock et al, 2012;Chen et al, 2009;Wang et al, 2013). The BWIM technique offers several advantages over the WIM method: 1) high weighing accuracy for gross weight, but not as good performance as WIM for axle weight measurement; 2) vehicles can pass freely, with minimal impact from travel speed on measurement results; 3) no interference with traffic or road surfaces, and no need for traffic restrictions on the bridge deck during installation (require traffic restrictions on the roads underneath the bridge).…”
