Glass/carbon FRP composites have been gaining popularity and acceptance in the bridge construction industry because of their high strength-to-weight, corrosion resistance, higher energy absorption, and competitive cost. A novel cost-effective moveable hybrid GFRP/Concrete deck system was proposed, and the concrete cast on the GFRP plate was simulated by sand irrigation test. The load-displacement relationship, stiffness and stress distribution were investigated to verify the feasibility of GFRP plate serve as the framework. Base on the test results, 3-D FEM is established to analyze the mechanical properties of the GFRP plate under construction process. The FEA results showed fairly good agreement with the experimental ones in terms of strength, deformation, and stiffness. Results confirmed that the stiffness and strength of GFRP plate under construction loading meet the requirements of relative code, and the FEM can be used to provide some guidance in the design of GFRP plate. |
