• Abstract:
  This research focuses on optimizing the design of cast-in-place, precast-panel (CIP-PCP) bridge decks by developing recommendations for standard ready-mix steel fiber reinforced concrete (SFRC) using domestically produced steel fibers. The project, stemming from the efficient and durable nature of CIP-PCP decks, builds upon prior work at the University of Texas and aims to minimize the reliance on conventional reinforcement in the CIP sections by adding steel fibers as an alternative reinforcement. The research team conducted extensive material and structural testing to identify the optimal SFRC and reinforcement layout for CIP-PCP bridge decks. Experimental results indicate that SFRC with fibers longer than 1.5 inches and a service residual flexural strength exceeding 480 psi can effectively replace the current reinforcement used in the interior span of CIP-PCP bridge decks. Further analysis of the overhang region suggests that SFRC has the potential to substitute for 31% of the existing Texas Department of Transportation (TxDOT) reinforcement.
