Abstract

In recent years, the occurrence case of fatigue crack has been an increase steel piers and steel deck, etc. in the road bridge. Depending on the site of the fatigue crack occurs, the crack is progress, cause brittle fracture. As a result, fatigue cracks will be a significant impact on the safety of the bridge. Therefore, finding them early, it is important to perform appropriate repair. This study is intended to develop a measurement method for detecting fatigue cracks. In this measurement method, first, by heating the steel members to open and close the cracks, and distortion difference before and after heating is measured using a digital image correlation method. This measurement method is a new detection method of crack defects of the steel member that does not require removal of the coating.
