Paper Abstract

Traditional point or quasi-distributed sensors can not cover the full scale monitoring of cables in service. A new kind of smart cable with functionality of full scale monitoring has been developed by combining the optical fiber-fiber reinforced polymer rebar (named as FRP-OF rebar) with the cable wires by using Brillouin sensing technology. Full scale cable's static experimental results show that the FRP-OF can discover the stress distribution along the cable under 60% of the ultimate cable loading. And also the repeatability is very good. The cable load gotten from the average monitored strain agrees well with that from the controlled force within error of 5%. This kind of smart cable shows perfect advantages such as durability, anti-corrosion, electro-magnetic resistance, low cost and fully-distribution sensing and so on, which can meet the long-term on-line health monitoring for practical cable.
