In this study, a self-sensing smart structure was developed with a novel approach. Electromagnetic wave based self-sensing structure designed by sending waves to the reinforced concrete structure through the reinforcement by using a coaxial cable. EM measurements were based on estimating the reflected EM waves through the reinforced concrete. Correlations between reflected EM wave, damage in reinforced concrete and strength development in concrete was estimated. According to test results, it was seen that with increasing crack width of reinforced concrete by applying monotonic load, reflection of EM wave through the reinforced concrete decreased. It was also seen that with strength development of the concrete, reflection of EM through the reinforced concrete increased. In the light of the findings of this study it can be said that, damage assessment and monitoring strength development of the reinforced concrete is possible in real time with applying the proposed novel technique.
