Abstract: Prior studies on the time-of-flight diffraction (TOFD) method have focused primarily on ground smooth, clean surfaces of steel. In practice, however, the surface of an existing bridge element will be covered with rust or ...

Abstract: The seismic performance of various retrofit schemes for nonductile reinforced concrete (RC) frames is investigated using inelastic static and dynamic response analyses of three prototype buildings. The structures considered ...

Abstract: In this study, the ultrasonic time of flight diffraction (TOFD) method to locate and size flaws in steel members was evaluated. This was done by measuring the location and depth of flaws implanted in steel plate specimens ...

Abstract: This paper presents the development of a project-level decision support tool for ranking maintenance scenarios for concrete bridge decks deteriorated as a result of chloride-induced corrosion. The approach is based on a ...
