Abstract

Abstract

In this study, we set up a finite element model for a carbon fiber reinforced polymer (CFRP)-concrete-steel composite structure under low-velocity impact load using ABAQUS. The analytic results from our model were found to agree well with the test results, thus capable of being used to simulate the mechanical performance of the structure. Using this model, we analyzed all the stages of the dynamic response of the specimen under lateral impact load, and investigated the effects of seven factors, such as impact height and hollow ratio, on the peak value and the platform value of the impact force and the mid-span residual deflection, using orthogonal analysis. We found that the impact height (impact energy) is the main factor influencing the peak value of the impact force; the residual deflection is affected by the interaction of the main factors including the impact height, the hollow ratio, the number of CFRP layers and the direction of CFRP; the main factor of the platform value of the impact force is the hollow ratio, and the anti-impact performance of the specimen gradually increases with the increase of the hollow ratio ranging from 0.3 to 0.7.
