| Fiber Reinforced Polymer, FRP, is a composite material composed of fiber and resin materials, and it is possible for engineers to enjoy the flexibility in material design. But the statistical assessment of material properties like strength and elastic modulus is necessary. Therefore, statistical response of FRP structural members subjected to tension, compression and bending moment should be investigated so that the framework of the ultimate design method applicable to conventional construction materials such as concrete and steels can also be developed for FRP composites. This study aims to investigate tensile, compressive and bending properties of Glass Fiber Reinforced Polymer, GFRP, formed into a channel cross section by hand lay-up molding method. At first coupon specimens cut from GFRP channel members are tested in tension and compression. Secondly, Monte Carlo simulation is curried out to evaluate tensile, compressive, bending response of FRP structural members based on statistical models of mechanical properties. As a result of evaluating the member performance of the FRP member by simulation, simulated member strength was found to be smaller than that from the material testing, but the simulated tensile and compressive elastic moduli were almost the same as those from the material testing. In addition, the simulated bending elastic modulus was slightly smaller than the tensile or compressive elastic modulus in the material test. |
