In this study, in order to investigate the influence of freeze-thaw action on impact resistant capacity of RC beams, falling-weight impact loading tests were conducted. Here, relative dynamic elastic modulus (RDM) of the concrete for evaluating frost damage index of concrete was set in the region between 100 % through 70 %. From this experiment, following results were obtained: i) if RDMs near the mid-span area of the beam were smaller than those in the other area, the beam tends to be failed accompanying with the upper concrete crushing; ii) if RDMs in the shear span area were smaller than those in the other area, the beam tends to reach the ultimate state with severe shear cracks opening; and iii) the failure mode of the beam may be largely depended upon the location of the damaged area.
