On Effective Placement of Acoustic Emission Sensor in Steel Framed Structure for Damage Detection

Abstract

For detecting structural damage in real-time using Acoustic Emission (AE) technique, effective placement of AE sensors is crucial from the perspective of structural health monitoring such that the number of sensors can be minimized. The present work attempts to find the most favorable position of a single sensor to detect the damage in a steel-framed structure in real-time. The obtained time-dependent response from AE testing has been used to study the AE event with respect to the position of a sensor from the source. The data comparison and analysis of the response data in the frequency domain provides an idea about the effective placement of the AE sensor in a steel-framed structure.
