Abstract : In this study, to improving the GFRP components stiffness and design requirements in response to different sections. Using the GFRP transform section beam and rectangle beam into the deck and square beam. Filling two types of the epoxy mortar. The GFRP components wrapping different fiber sheet consisting of carbon fiber and basalt fiber. A series of beam tests will conduct under 3-point bending test to know the force-displacement relationship, stiffness, failure strength and failure mode of the combination beam. The Timoshenko beam theory and Euler beam theory were applied to analyze the profiles, using material properties estimated. Finally compare the experimental result and numerical result. Both results show the stiffness of GFRP beam filled with epoxy mortar is twice larger than GFRP beam. • Comparing the P-δ relationships of FRP beam with Euler theory • Comparing the P-δ relationships of Combination of FRP Components • Experimental results of Combination Deck • Comparing the P-δ relationships of FRP deck with Timoshenko theory • Conclusions The FRP combination of the deck and beam components infilled the rctangle beam can increase the moment of inertia (stiffness), and ultimate load. The mechanical behavior of using the epoxy mortar to make the second type of filling components is better than the first type on the FRP combination components . For the FRP combination components, wrapping the FRP beam with 2-layer (90o) fiber can be avoid the destruction occurred on the corner side. Using the Euler and Timoshenko beam theory to calculate that comparing with the experimental results is approximate. • Experimental results of Combination Beam
