Structural characterization of hybrid fiber-reinforced polymer-glulam panels for bridge decks
Glued laminated (glulam) wood material has been used in bridges for approximately 30 years. Glulam panels have been used in bridge decks, by being supported on steel or glued laminated stringers. Fiber-reinforced composites have offered new opportunities to repair or strengthen existing wood structures in buildings and bridges. It was found that FRP-glulam beams with sufficient tension reinforcement not only exhibit significant strength increases, but also they develop wood ductile compression failure, rather than the typical brittle tension failure of wood. In addition to improving strength and ductility, the reinforcement of glulam panels with FRP composite skins, based on the concept of sandwich construction, is expected to enhance durability performance. Based on the research work presented in this paper, the following conclusions are drawn: An experimental protocol based on a two-span continuous bending test configuration is recommended to characterize the stiffness, ductility, and strength response of FRP-glulam panels under simulated traffic loads. The proposed beam nonlinear model, based on the layered moment-curvature analysis, proved to be a valuable tool to characterize the response of the panel cross section and to predict the ultimate load capacity.
