A Review on Analysis of Damage Diagnosis and the Vibration Characteristics of Steel Bridge Structures

Cracks or crevasses in girder steel bridges caused by moist environmental issues such as corrosion have the possibility of causing structural destruction, resulting in the loss of unanticipated events, assets, and human life. This obliteration can be overlooked if cracks are resolved early. The cracks in the bridge girder alter its strength and vibration characteristics. The current study examines various studies in the field of crack detection/damage detection that have been conducted using various numerical and experimental techniques. Analysis of finite elements (FEA) can be highly useful in protecting a structure from damage and cracks. The review deals with the investigation of damage commencing from environmental exposure conditions which can be studied via various numerical and experimental investigations by means of simulation techniques. By dint of these software-aided techniques, the research can be carried out in a simple and effortless manner. FEA enables engineers to conduct the simulation of a designed model rather than creating a physical model for testing. The current study looks at the effect of damage initiation and propagation using software-operated techniques The Applications of finite element methodology, which requires a software package for dynamic simulations, are presented and highlighted in terms of innovation and future research in studying crack attributes of natural and mode shapes.
