  • Abstract:
    The goal of this study was to develop and evaluate the performance of retrofit techniques for existing steel ; bridges that have already sustained damage due to distortion-induced fatigue, or are anticipated to experience ; distortion-induced fatigue cracking within their design life. A second goal was to evaluate the use of new ; technologies and materials for repairing distortion-induced fatigue damage in steel bridges. ; While a number of retrofit techniques exist for repairing distortion-induced fatigue cracking, many of ; them require partial or full bridge closure to perform the repair. The retrofits developed under this project are ; intended to be able to be installed with minimal disturbance to traffic. Four primary subject matters are ; reported on within this document: (1) the development of the “angles-with-plate” distortion-induced fatigue ; repair; (2) development of fiber reinforced polymer (FRP) repairs for distortion-induced fatigue and in-plane ; fatigue; (3) development of Piezoelectric Induced Compressive Kinetics (PICK) technology for treatment of ; crack-arrest holes; and (4) a series of analytical investigations aimed at better understanding distortion-induced fatigue susceptibility of skewed bridge systems.
