As the much of our nation’s infrastructure approaches the end of its design life, designers and researchers are looking for new, innovative, and economical ways to approach bridge design. Due to the corrosive nature of steel contained in reinforced concrete structures such as bridge deck slabs, new methods of design are currently being researched as potential alternatives. Over the last several decades, experiments have been conducted on concrete deck slabs that suggest that flexure is not the primary behavior that bridge deck slabs use to resist load as commonly thought. Rather, studies have shown that an internal phenomenon referred to as arching action is actually how these slabs resist load. As a result, an empirical design method exists that only requires approximately half the amount of steel reinforcement traditionally used. Additionally, both traditional strength and empirical designs exist that utilize Glass Fiber Reinforced Polymer (GFRP) reinforcement that is corrosion resistant. Furthermore, ample Canadian research exists that suggests that through the use of the arching action technology, all internal reinforcement can be removed from the deck. This methodology is referred to as steel-free deck design. This laboratory experimental program consisted of testing specimens designed by the various methodologies to observe their behavior at a Service Level.
