Outline of Final Research Achievements

In this study, in order to establish a simple and engineered analysis method for appropriately evaluating the dynamic response characteristics of steel and/or reinforced concrete (RC) beams under impact loading, impact response analysis method based on a fiber element approach was proposed. An applicability of the proposed method was discussed comparing with the experimental results of small-scale H-shaped steel and RC beams having different impact velocities of impact striker. From this study, the following results were obtained: (1) applying the proposed method, the deflection behavior of the beams can be appropriately predicted; and (2) the method may be able to use as a tool for evaluation of the dynamic response characteristics of the steel and/or RC beams under the impact loading.
