Abstract

A damage identification method based on anti-resonance frequency change was proposed. In the results of harmonic vibration response analysis, it was shown that anti-resonance frequencies were notably changed by slits in a concrete beam. The slits were made into the concrete beam specimens to examine the adequacy of proposed method. In the experimental results, it was shown that a damage location in concrete beam specimen was given by relationship between resonance and anti-resonance frequency changes. From the forced vibration tests of the concrete and steel road bridges, it was confirmed to be able to measure anti-resonance frequencies in these bridges by using a portable shaker.
