The dynamic response of Reinforced Concrete (RC) and Carbon Fiber Reinforced Polymers with Reinforced Concrete (CFRPRC) is studied. These tests were performed on RC members covered in one to six layers of CFRP. Once the energy is high, the two components' deflection-time histories are produced. It increases component impact resistance in studies. Component deflection is reduced by carbon fiber reinforced polymer (CFRP). RC members shear while CFRPRC components bend due to significant concrete damage. It fractures more easily when wrapped with CFRP. The model's predictions match the tests adequately. A numerical simulation study looked at the impact force of members under unequal-span lateral collisions. Regardless of impact velocity, lateral impact on an unequal span induces severe shear failure of RC members. However, CFRPRC component bending deformation reflects impact velocity. Increasing the reinforcement ratio of RC members has little effect on the impact resistance of CFRPRC components. To avoid steel fracture, greater reinforcing ratios are used. |
