摘要：

This paper presents experimental and numerical studies on the behavior of concrete filled circular steel tubular (CFCST) members under lateral impact loading. Fourteen CFCST member specimens were designed, fabricated and tested using a Drop Hammer Impact Test Machine in a simple double-supported boundary conditions. The main parameters include the outer diameter of CFCST member, the thickness of steel tube and the height of drop hammer. The failure modes, the impact force, the impact force time history curves and the strain time history curves were investigated to evaluate the behavior of CFCST member under an impact load. A finite element analysis (FEA) model of CFCST member under lateral impact loading was established using ABAQUS software, and the accuracy of the proposed model was verified by a comparison with the test results. The response of the specimen under impact loading simulated by FEA model, matches well with the test results.
