Abstract

To more accurately investigate the dynamic response of RC beams under concentrated impacts, the nonlinear dynamic response characteristics of a clamped beam were numerically simulated by the finite element analysis software ABAQUS with the consideration of the strain rate effects of concrete and steel bar and the influence factors such as the height of the beam section, the reinforcement ratio, the contact area, the impact velocity and mass of the hammer. The results show that the contact area and the impact velocity have evident influence on the impact load and the structural displacement, the height of the beam section and the reinforcement ratio have limited influence on the response, and the mass of the hammer has little influence on the impact loads.
