겹침이음된 GFRP 보강근으로 보강된 콘크리트 보의 휨 거동에 대한 해석적 연구

Abstract

Corrosion of the steel reinforcement in a cold and saline environment leads to the overall deterioration of reinforced concrete structures. To avoid such deterioration, Glass Fiber Reinforcement Polymer(GFRP) rebars are used in place of steel reinforcement. In the present paper, in order to examine the effect of reinforcement ratio of concrete beam reinforced with lap-spliced GFRP bar, nonlinear finite element analyses are performed.
