• Abstract:
  Researchers investigated the behavior of the double composite superstructure system. The system utilizes rolled beams in combination with a reinforced concrete slab, resting on the bottom flanges of the beams, to allow for longer spans to be built using rolled beams. To assess the full potential of double composite bridge systems, an analytical formulation, validated through numerical finite element analysis, was developed to capture the full nonlinear behavior of the bridges. The effect of some parameters relevant to performance, such as the use of prestressing tendons and ultra-high-performance concrete, was investigated.
