  • A review of B-WIM as a SHM applications on bridges [Elektronski vir]
    Hekič, Doron ; Anžlin, Andrej, gradbenik ; Žnidarič, Aleš
    Bridge Weigh-in-Motion (B-WIM) systems are installed on the bridges to weigh the passing vehicles in motion without traffic interruption. Besides weighing the freight traffic with equivalent accuracy ... to the pavement WIM, they can be designed to monitor bridge performance under traffic loading simultaneously. This is characterised by performance indicators (PI), most often influence lines, dynamic amplification factors (DAF) and load distribution factors. If suppose these PIs are adequately extracted from B-WIM measurements, the B-WIM takes the role of a Structural Health Monitoring (SHM) tool, in which the bridge performance monitoring can be correlated by the known axle loads of the crossing vehicles. While the traditional B-WIM systems measure strains in the bridge superstructure, some recent methods use accelerometer measurements. The conventional SHM systems typically include various types of sensors, including accelerometers, strain and temperature gauges, inclinometers, etc. They are generally installed on the most important or critical structures only, while B-WIM systems have the potential also for smaller, less important bridges. This paper aims to present the B-WIM capabilities, which are developing towards SHM and are no more limited to just weigh-in- motion the heavy traffic. In the beginning, the paper presents SHM and B-WIM definitions and reviews the PIs that can be extracted from B-WIM measurements. Later, selected studies where B-WIM is used for fatigue lifetime assessment are presented, and finally, two applications of B-WIM for damage detection reviewed.
