Abstract

To finally obtain the overall and fast recognition method for the electrochemical corrosion of reinforced concrete (RC) structures, the complex function algorithm is established to approximate the corrosion transfer function in frequency domain, and then the influence of Z_CPE, Z_W, R_ct and R_c in the universal equivalent circuit (EC) R_c((R_ctZ_W)Z_CPE) on the time response is discussed in detail. The results indicate that the polynomial complex function can successfully approximate the corrosion transfer function with the given accuracy. The response of R_c((R_ctZ_W)Z_CPE) in time domain can be achieved by the inverse Laplace transform of the polynomial complex approximation function.
