BROAD STREET BRIDGE
Special Damage Inspection
CLIENT/REFERENCE: RI Department of Transportation
Commonwealth Engineers & Consultants, Inc. was retained to provide in depth special damage member inspection of steel stringer beams struck by a truck.
Impact occurred at a point approximately 13 feet from the end support where the bottom flange displaced laterally approximately 13.5 inches from its original alignment. The girder web was bent, beginning approximately at mid depth of the bearing stiffener at the end support,
extending up to a point several inches from and along the top flange, and back down to approximately mid depth at the first intermediate diaphragm. The total length of the girder affected by the impact extended approximately 28 feet from the end support.
Based on the data collected from our field inspection CE&C prepared a structural evaluation, assed the damage, investigated possible repair schemes, and provided appropriate recommendations for repair and/or replacement. Two repair alternatives consisting of heat straightening and beam replacement were investigated. Each repair alternative was evaluated with respect to feasibility, economics, and construction duration. CE&C prepared a final report, recommending the girder be repaired by heat straightening.
