Optimal Locations of Sensor for Structural Health Monitoring of a Steel Truss Using Acoustic Emission Technique: An Experimental Investigation
Acoustic Emission (AE) technique, which is gaining popularity in recent years, is a non-destructive structural health monitoring technique that can detect defects within a structure in real time. This technique has emerged with immense potential for continuous real time monitoring of structures. However, such continuous monitoring involves use of AE sensors, which are very costly. Consequently, monitoring of huge engineering structures becomes a costly affair in terms of the number of sensors as well as the other relevant hardware for acquisition of data and the computational system for processing and analysis of recorded data. In order to overcome this difficulty, only a limited number of sensors is required to be used. Therefore, to make the continuous monitoring of the structure effective using limited numbers of sensors, it is imperative that the sensors are placed at the optimal locations on the structure. In view of this, the current study makes an effort to determine the optimal locations of AE sensors on a model steel bridge truss through experimentation. The study involves placing of AE sensors on different pre-defined nodes of the laboratory scale model of the steel bridge truss and obtaining waveform signal for a simulated AE source. Based on statistical analysis of the obtained waveforms, the optimal position for a single sensor on the steel bridge truss is obtained. The methodology may be used as a guide to obtain optimal locations of AE sensors on real life bridge trusses.
