Analysis of Behavior in RC Beams Strengthened by Gass-Fiber Reinforced Epoxy-Panel

유리섬유보강 Epoxy-Panel로 보강된 철근콘크리트보의 거동해석

The Glass-Fiber Reinforced Epoxy-Panel(GFREP) is a composite material developed for repairing and strengthening of RC structures. The objective of this study is to verify the applicability of finite element modeling technique to analyze behaviors of RC beams strengthened by the GFREP. In this study, the basic material properties obtained by experiments on the GFREP and the reinforced concrete constitutive models were considered and the comparison between analyses and experiments of RC beam specimens strengthened by the GFREP was made. Although analysis method in this paper was reasonably good, the necessities which can consider the effect of plate-end shear and plate separation were recognized.
