TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2131 includes 15 papers that explore light support structures for traffic signs and signals; steel bridges; concrete bridges; and culverts. Among the specific topics discussed for these structures are their design, testing, seismic design, and properties of materials used in these structures, including concrete, steel, polyvinyl chloride pipe joints, carbon fiber-reinforced polymer, glass fiber-reinforced polymer stay-in-place forms, and the fiber-reinforced polymer–concrete bond.
