Abstract
Acoustic Emission (AE) monitoring is one of the possibilities to detect the crack distribution inexisting concrete structures. However, the conventional method requires further destruction likeopening of new cracks or propagation of the existing cracks. In this paper, a new strategy ofusing local cumulative AE activities during unloading to track the crack trajectory is proposed.With this strategy, a relatively low load level which does not cause further destruction to thestructure is needed. The possibility of this strategy is experimentally examined using a realscale beam of 10-ton damaged under cyclic loading. For calibration, the crack opening ismeasured by Digital Image Correlation (DIC). The crack patterns detected by the new strategyand DIC show good agreement.
