FRP composite bridge deck panels offer high strength, corrosion resistance, and weather durability, making them attractive for new construction and bridge retrofits. This study assessed the force‑deformation behavior of FRP panels under AASHTO MS 22.5 truck wheel loads up to failure. Sixteen FRP panels and four conventional reinforced‑concrete panels were tested, with flexural, shear, and deflection responses compared to Ohio DOT criteria and their rigidities calculated. All panels met performance criteria, exhibited safety factors between 3 and 8, and their responses under service, factored, and cyclic loads were documented.
Fiber-reinforced polymer (FRP) composite bridge deck panels are high-strength, corrosion resistant, weather resistant, etc., making them attractive for use in new construction or retrofit of existing bridges. This study evaluated the force-deformation responses of FRP composite bridge deck panels under AASHTO MS 22.5 (HS25) truck wheel load and up to failure. Tests were conducted on 16 FRP composite deck panels and four reinforced concrete conventional deck panels. The test results of FRP composite deck panels were compared with the flexural, shear, and deflection performance criteria per Ohio Department of Transportation specifications, and with the test results of reinforced concrete deck panels. The flexural and shear rigidities of FRP composite deck panels were calculated. The response of all panels under service load, factored load, cyclic loading, and the mode of failure were reported. The tested bridge deck panels satisfied the performance criteria. The safety factor against failure varies from 3 to 8.
