Structural Health Monitoring (SHM) is a technique used to assess the condition and integrity of a structure continuously or periodically, such as buildings, dams, aircraft, pipelines, bridges and more. The primary goal of SHM is to detect and identify any possible damage, deterioration or anomalies in the structure’s material. One of the best tools for real-time monitoring systems is the Acoustic Emission (AE) technique. This technique is an effective tool for the assessment of anysystem without detriment to the material condition. In civil structures, concrete mainly carries high compressive strength, but in terms of tensile strength, it is very weak and, hence, cracks easily. Cracking is one of the common indications of distress, which has the greatest impact on the concrete structure and early symptoms of failure structure. In this concern, this paperaims to be a focused overview of the application of AE in civil structure monitoring. The main topic of this paper is previous research on AE in civil structure since many researchers have shown an increased interest in AE. Research on theAE technique continues today in the pursuit of enhancing the performance and condition of civil structures. It can be concluded that applying AE in civil structure monitoring enhances safety, reduces maintenance costs and ensures the long-term sustainability of the structure. © 2024 Seventh Sense Research Group®
