In order to confirm the accuracy of various numerical analysis methods for estimating impact resistant behavior of RC beams, Round-Robin pre/post-analysis for impact behavior of rectangular RC beam subjected to a falling-weight impact force was conducted. Representative six researchers including professors were jointed for this research project, in which analysis methods used here were: two two-dimensional analysis methods using beam element and multi-layered shell element; two-dimensional discrete element methods; and three-dimensional finite element methods. From this research project, it was recognized that all methods used here can be available for evaluating the impact behavior of the RC beam with a good accuracy when a suitable constitutive model, damping factor, and boundary conditions may be used.
