Crack classification in concrete beams using AE parameters
Abstract
The acoustic emission (AE) technique is an effective tool for the evaluation of crackgrowth. The aim of this study is to evaluate crack classification in reinforced concrete beamsusing statistical analysis. AE has been applied for the early monitoring of reinforced concretestructures using AE parameters such as average frequency, rise time, amplitude counts andduration. This experimental study focuses on the utilisation of this method in evaluatingreinforced concrete beams. Beam specimens measuring 150 mm x 250 mm x 1200 mm weretested using a three-point load flexural test using Universal Testing Machines (UTM) togetherwith an AE monitoring system. The results indicated that RA value can be used to determine therelationship between tensile crack and shear movement in reinforced concrete beams.
