Novel distributed cable sensors for detection of cracks in RC structures
Based on the crack-induced change of their topology, two prototype cable sensors were designed and fabricated. Prototype I can be used to detect cracks induced by static or cyclic loading while Prototype II is applicable for all type of loadings with a special memory feature under dynamic effects. Both sensors have been demonstrated in the laboratory sensitive to cracking, from visually undetectable to excessive crack, and able to accurately identify the location of cracks. Future research will be directed to further enhance the uniformity of sensor performance by using a spray-up type of plasma coating or automatic manufacturing of sensors. For realtime monitoring of damage evolution, fast ETDR measurement instruments must be developed. In addition, crack sensors must be validated in field conditions and demonstrated for their superior performance in full-scale structures.
