Abstract

Structure health monitoring of cable-stayed bridges has been developing for decades but there are still no practical monitoring schemes for cracks in steel wires of stayed cables. Stress analysis based on finite-element analysis and fracture mechanics tries to find the relationship between cracks and redistribution of forces among cables and steel wires. Cable force monitoring systems based on magnetic flux sensor, FBG technology have been widely used in present. But to monitor cracks in cables, the existing force monitoring system is not sufficient, cable force monitor, wire force monitor and data processing center are needed.
