Y.J. Yu, J-Y Cho, “Analysis for Verification of Previous Empirical Equation about Behavior of RC Beam under Impact Loading”, Proceedings of the Korea Concrete Institute, 29-1 : 717-718, 2017.

The behavior of RC beam under impact loading is different from that of static state. Thus, various experiment and analysis study have been performed and proposed empirical equation of predicting the behavior of RC beam subjected to impact loading. In this study, analysis was performed to verify the effectiveness of previous empirical equation
