A fracture critical bridge is defined by the Federal Highway Administration (FHWA) as a bridge with one (or more) steel member in tension whose failure would lead to partial or complete collapse of the bridge. According to the National Bridge Inventory Database of FHWA, the transportation infrastructure in the United States has more than 18,000 fracture critical bridges. Resensys offers wireless remote monitoring using SenSpot sensors which for concurrently monitoring strain, temperature, and inclination on structural members of fracture critical bridges.
Resensys wireless technology featured in Bridge Design & Engineering magazine in August 2016. Resensys technology offers easy-to-install wireless devices for long-term monitoring of fracture-critical bridges. It can monitor strain and temperature on girders, truss members, gusset plates, floor beams, stringers or other members to determine strain variations caused by temperature change and live traffic, which can be used for early stage detection of issues related to fatigue or formation of cracks. SenSpot data can also help determine load-bearing capacity of a bridge as well as detecting occasional overstrains caused by vehicles violating a bridge's maximum allowed load. In addition to strain, Senspot sensors can be used to monitor bearings, piers, expansion joints or the status of existing cracks in a bridge.
