This feasibility study examines if the tensile stress on bonded PSC tendon could be estimated by means of measuring electrical impedance. The impedances of the five beam specimens with different tensile stress levels were measured. As tensile stress on the tendon increases, the impedance of the tendon considerably decreases. Thus, it seems that the estimation of the tensile stress on the tendon could be possible by measuring the electrical impedance.
