Impact Response Analysis of RC Beams by Means of Fiber Element Approach

Abstract

In this study, in order to establish a simple and engineered analysis method for appropriately evaluating the dynamic response characteristics of RC beams under impact loading, impact response analysis method based on a fiber element approach was proposed. An applicability of the method was discussed comparing with the experimental results of a total of eleven small-scale RC beams having different dimensions and 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 then 2) the method may be able to use as a tool for evaluation of the dynamic response characteristics of the RC beams and/or frames under the impact loading
