Book excerpt: An experimental investigation was undertaken to determine the effects of transverse confinement using glass fibre reinforced polymer and steel bars in deck slabs. Researchers in Nova Scotia and Ontario have expressed the opinion that only the bottom transverse layer of reinforcement is required for strength and safety of conventionally reinforced deck slabs. Further, they have hypothesized that the bottom transverse reinforcement acts as a lateral tensile tie, in a manner similar to that of steel straps in steel-free deck slabs. Studying the transverse confinement provided by the lateral restraints, which enables the arching action in conventionally reinforced and steel-free bridge deck slabs, will facilitate innovative and increasingly durable designs using advanced composite materials such as GFRP. The first component of the study was to assess the function and effectiveness of each layer of steel reinforcement in conventionally reinforced deck slabs. The second component was to determine if GFRP bars could also be used to perform the same function as the steel straps and lower transverse steel bars, based on equivalent axial stiffness.
