Abstract

Applicability of acoustic emission (AE) technique for evaluation of fatigue damage was examined in reinforced concrete (RC) slabs under cyclic loadings in both laboratory and real structure in service. The fundamental test performed in laboratory showed that cracking process can be practically monitored by the measurement of AE signals. The analysis of the relationship between loading phase and AE activity indicated that the final stages of the fracture process can be evaluated by detecting AE signals generated near the minimum loading phase. The comparison of the result from the real structure and that from the laboratory specimen demonstrated that AE energy can be an effective parameter for evaluation of fatigue damage in RC slabs in service.
