APPLICATIONS OF A BRIDGE MEASUREMENT SYSTEM

Recent efforts to record bridge strain histories due to highway truck traffic have been prompted by modifications in fatigue code, introduction of high-strength steel alloys and more fatigue-sensitive welded bridge details, and increases in truck weights and volumes. This study was designed to improve measuring and processing systems and to expand both the amount and the type of information recorded in bridge studies. Truck headway and type, lane location, and corresponding strain record and maximum stress range were recorded and processed on 10 slab-girder bridges for almost 20,000 truck passages. This paper describes the measurements and processing system developed and discusses applications of the measurement data to fatigue design including impact, girder load distribution, fatigue life stress cycles, predicted and measured stresses, and the potential for weighing trucks in motion on bridges.
