摘要：

In this study, the performance of glass fiber-reinforced epoxy resin (GFRP) reinforced circular steel tubes under low-velocity transverse impact loads was examined using both numerical and experimental methods. In the tests, the energy dissipation capacity and bearing capacity of steel and GFRP reinforced steel tubes were compared. Furthermore, failure modes of the specimen and the effects of steel thickness and winding angle (the angle between the axis of the tube and tangential direction of the winding fiber) were discussed. The impact process was simulated through finite element simulation. Additionally, the influence of steel tube thickness and outer diameter, GFRP thickness and winding angle, specimen length, and the mass of the drop hammer and impact velocity was analyzed.
