Fatigue Resistance of Rib to Deck Welds in Steel Orthotropic Decks

项目名称：	Fatigue Resistance of Rib to Deck Welds in Steel Orthotropic Decks
摘要：	This research project will develop welding procedures for fabrication of steel orthotropic bridge decks. The project will focus on the quantifying the variables affecting the fatigue resistance of rib-to-deck welds. Originally the project was to evaluate the Hybrid Laser Arc Welding (HLAW) process for re-decking the Walt Whitman Bridge in Philadelphia, but project did not get results quickly enough and the scope was expanded to also include conventionally used steel fabrication welding processes. The project is now evaluating the fatigue resistance of rib-to-deck welds made using HLAW, SAW, and GMAW welding processes at various weld penetrations of fillet, 20%, 40%, 60%, 80% and 100% weld penetration.
