• Abstract:
  One common form of costly bridge maintenance is repairing corroded steel beam ends under leaking joints. Recently, the University of Connecticut and the Connecticut Department of Transportation have developed a practical repair strategy in which shear studs are welded to undamaged sections of the corroded steel beam and then ultra-high-performance concrete (UHPC) is cast around the corroded steel beam end. The purpose of this project was to evaluate how UHPC repairs on steel beam ends can be modified to make the beam ends easier to construct in the field, either by Virginia Department of Transportation (VDOT) work crews or by contractors. The two modifications that this project focused on included using other types of fiber reinforced concretes (FRCs) in place of UHPC and using threaded rods instead of shear studs to transfer load from the steel beam to the FRC panels. A literature review showed that very high-performance concrete and engineered cementitious composite have the necessary strengths for FRC beam end repairs and offer convenience, availability, and cost savings advantages compared with UHPC. Threaded rods were also found to have sufficient strength, ductility, and fatigue resistance to be used in FRC beam end repairs. They offer ease of installation, worker and environmental safety, and cost savings advantages compared with welded shear studs.
