ABSTRACT

In this study, a novel damage evaluation method for concrete structures is introduced, which is based on the rising rate of acoustic emission. This method leverages the fact that when a concrete structure is subjected to stress, acoustic emissions increase, and the rate of this increase can be correlated with the extent of damage. To validate the effectiveness of this proposed method, a seismic damage test was conducted on a frame shear wall structure, which is a common and critical component in many building constructions. The results of the test clearly demonstrated that this method can accurately evaluate the damage status of the structure. More importantly, it has the capability to effectively locate areas where significant damage has occurred. This makes it a potentially valuable tool for post-disaster assessment and structural health monitoring, as it can help engineers and inspectors quickly identify and prioritize areas that require repair or further investigation. Overall, this study presents a promising approach to enhance the safety and reliability of concrete structures in the face of seismic events.
