摘      要：In the past,glass fiber-reinforced polymer(GFRP)-reinforcement has been successfully applied in reinforced concrete(RC)structures where corrosion resistance,electromagnetic neutrality,or cuttability were *** investigations suggest that the application of GFRP in RC structures could be advantageous in areas with seismic activity due to their high deformability and ***,especially the low modulus of elasticity of GFRP limited its wide application as GFRP-reinforced members usually exhibit considerably larger deformations under service loads than comparable steel-reinforced *** overcome the aforementioned issues,the combination of steel and GFRP reinforcement in hybrid RC sections has been investigated in the *** on this idea,this paper presents a novel concept for the predetermination of potential plastic hinges in RC frames using GFRP *** analyze the efficiency of the concept,nonlinear finite element simulations were *** results underscore the high efficiency of hybrid steel-GFRP RC sections for predetermining potential plastic hinges on RC *** results also indicate that the overall seismic behavior of RC structures could be improved by means of GFRP as both the column base shear force during the seismic activity as well as the plastic deformations after the earthquake were considerably less pronounced than in the steel-reinforced reference structure.
