Advances in Research

Conducting damage identification and detection of engineering structures can help to identify the location of structural damage and assess the extent of the damage, providing a basis for the reinforcement and repair of the structures. This ensures the normal operation of engineering structures and, in turn, protects people's lives and property. Therefore, the research on structural damage identification methods has always been an important research topic in the field of civil engineering. The existing damage identification methods can be roughly classified into the following categories: damage identification based on structural dynamic response, structural damage identification based on model updating techniques, and structural damage identification based on artificial intelligence methods. This paper reviews the development history of existing methods, expounds on several common damage identification methods and their advantages and disadvantages, and makes a prospect for the development of structural damage identification methods according to the current research status at home and abroad. It can provide a reference for the research and application of damage identification methods.
