Paper Abstract

Acoustic emission test monitoring is an effective non-destructive technique. In this paper, a new signal processing method which is damage alarming index for AE signal based on fractal theory was proposed and the Pseudo-static experiments of a reinforced concrete column (RCn4) and a reinforced nano-concrete column (NMRCn4) were performed. The results show that the fractal theory-based damage alarming index has the ability of alarming structure damage failure. The damage occurring and developing location of the specimens also can be estimated by the diversity of the values of fractal theory-based damage alarming index of different detectors.
