Abstract: Twelve hot-rolled H-shaped steel column specimens were tested under two different boundary conditions and lateral impact along their major axis using a DHR9401 drop-weight-impact-tester. Time-history curves and residual deformation of specimens were recorded. Based on the experimental data,the dynamic behaviors of steel columns were analyzed and discussed. The test results showed that the overall bending derformation occurs on fixed-simply supported specimens under lateral impact load; furthermore,for the specimens padded with a rigid constraint platform under their flange,local buckling deformation occurs at the collision position; boundary condition of a specimen has an obvious influence on its impact force time-history; overall bending deformation or local buckling deformation of specimens obviously increase with increase in impact energy,both of them reveal a linear relationship; specimens exhibit a good antiimpact performance and ductility in tests.
