Abstract
<p>This paper investigates the responses of circular CFRP-RC components when subjected to an asymmetrical impact force. The impact performance of CFRP-RC components was investigated using drop-hammer impact test equipment. The failure mechanism and dynamic response properties of the CFRP-RC components were considered critical to obtaining. Three specimens were used in the experiments. The specimen's crack propagation pattern, failure mechanism, impact force, and deflection time history curves are all obtained. The test results indicate that shear fractures occur between the impact point and the adjacent support. The failure mode of reinforced concrete components transforms from bending to shear related to the unequal span impact load. A finite element modeling method was proposed and demonstrated efficiently. The control variables were used to analyze the failure mode and mechanism. Once the impact velocity or the number of CFRP layers decreases, the component fails in shear rather than bending. During an impact load, the internal force distribution of components differs significantly from that of a static load. The mechanical properties and failure mechanisms of CFRP-RC components are investigated using test and FE analysis. The failure modes of the components and the distribution and development of bending moments, shear forces, reinforcing strain, and energy consumption are all investigated.</p>
