Polyurea resin is one of the possible material that can absorb impact energy by their large deformability. In order to confirm the efficiency of polyurea resin for impact load, low speed weight drop test on RC cantilever beams with and without polyurea resin were performed. After that, impact behavior of them were simulated by improved SPH method and discussed with respect to shock absorbing effect of polyurea resin. Furthermore, middle speed impact test for RC slab with and without polyurea resin were also conducted. From these two kinds of experiments, it is confirmed that shock absorbing effect of polyurea resin is relatively small under low speed impact test however it becomes large under middle speed impact test. In addition, proposed analysis method was verified under low speed impact case and adequate dynamic model of polyurea resin is needed for middle speed impact problem.
