Abstract:

Currently, all State and local agencies responsible for the maintenance of suspension bridge cables base their maintenance plan mainly on previous experiences and on information from limited inspections. Usually, the exterior covering of the cable is visually inspected biannually. If deterioration problems are suspected and if the maintenance budget allows, then in-depth inspections are conducted. The cable is then unwrapped at a few locations along the cable length and is wedged into its center. Next, a visual inspection of the wires’ conditions is performed, and in some cases, a few wires are cut and removed for laboratory testing. Unfortunately, current visual inspections do not provide an adequate amount or sufficiently reliable data, indicating the need for innovative non-destructive testing (NDT) and sensing technologies that can provide an immediate, comprehensive, and reliable assessment of cable conditions and their evolution with time either directly or through measuring-related variables (i.e., temperature, humidity, etc.).
