Sensitivity of lateral impact response of RC columns reinforced with GFRP bars and stirrups to concrete strength and reinforcement ratio

•First investigation of impact behaviour of GFRP RC Columns.•Reinforcement ratios greatly affect failure modes and impact-resistant capacity.•High strength concrete may undermine performance of columns due to its brittleness.•GFRP reinforcements can be used to reinforce concrete column under impact...
