In order to establish a rational numerical analysis method for appropriately evaluating the impact resistant behavior of the steel posts for rockfall protection fences installed into the protection walls, 3D elasto-plastic impact response analyses were conducted taking impact velocity of the impacted weight as variables. The applicability of the proposed method was investigated by comparing with the experimental results in the case of the through-type steel posts. From this study, it is confirmed that the impact resistant behavior of the steel posts can be properly simulated by applying the proposed method.
