Abstract: Continuous reinforced concrete slab bridges rely on reinforcing steel bars near the top of the deck over the piers to carry negative moment. Transfer of forces in these bars may be jeopardized by deterioration and repair ...

Abstract: A fast-track project delivery strategy is designed to leverage the ability to execute the design, procurement, and construction phases simultaneously to substantially reduce the overall project duration. The successful ...

Abstract: There has been a growing interest in using large-diameter strands to alleviate congestion by using fewer strands, reduce the total number of girders by increasing girder spacing, increase the span length, and allow shallower ...

Abstract: Seven-wire prestressing strands are commonly used to pretension concrete bridge members. While the industry standard is 12.7-mm (0.5-in.) or 15.2-mm (0.6-in.) diameter strand, interest in developing greater pretensioning ...

Abstract: Lean production techniques developed by Toyota Motor Corporation have been widely applied in the manufacturing sector to reduce waste, ensure just-in-time delivery, create effective value streams, and ensure continuous ...

Abstract: An evaluation of concrete reinforcing bar fatigue provisions of AASHTO

Abstract: Prior to the 2013 Interim Revisions of the AASHTO LRFD Bridge Design Specifications [AASHTO (2013). Interim Revisions to AASHTO LRFD Bridge Design Specifications, 6th Ed., Washington, DC], the value of reinforcing steel ...

Abstract: Pretensioned concrete girders—especially those having large prestress forces—are susceptible to flexural cracking at their top flanges near the girder end as a result of prestress transfer. One effective method to reduce ...
