碩士 / 國立臺北科技大學 / 土木與防災研究所 / 100 / This study presents the use of Fiber Reinforced Plastic (FRP) composite bridge deck subjected to three-point bending test to determine the mechanical behaviors as well as the failure modes. Test results were compared with the results taken from Finite-Element Method (FEM) analysis software to verify the accuracy of the Finite-Element model. Three different FRP composite bridge panel types were used for the experiments. One is the prototype panel, an epoxy mortar-filled FRP panel, and the third is an epoxy mortar-filled FRP panel wrapped with carbon fiber. A Load Cell and Dial Gauge were used in the three-point bending test to measure the force-displacement relationship of each specimen and also make a comparison of the failure mode. The results of the prototype FRP bridge deck showed a linear force-displacement relationship; no obvious failure at yielding point. The FRP composite bridge deck filled with different fillers indicated that the infilling materials effectively improved the ultimate strength and stiffness of the original composite deck. And also, the wrapping of the third kind of FRP composite bridge deck with the different fiber patches FRP deck version of the outer layer coated fabric showed that the fiber wrapping increased the confinement and thus enhanced the ultimate strength of the component. Finally, in this study, numerical analysis software, ANSYS, was used to compare the finite element analysis results with that of the experimental results. The results of the comparison on analysis and experiment are very close; which verifies the finite element model''s accuracy.
