Steel wire ropes as crucial components of cable-stayed bridge and hoist elevator always bear the tensile load.Corrosions or fractured wires occurred in the strands due to the moist environment and mechanical wear may result in a reduction in the load-carrying capacity of the structure that can lead to collapse.The ability to monitor the stress level and integrity of steel wire rope can help to assess the deteriorating state of such structures that may provide suggestions on when to replace them and how to prolong their useful lifetime.Ultrasonic guided wave technique has been proven to have great potential for flaws detection in wire ropes.
