AbstractThe design method for impulsive wave pressure with very short duration time is important to prevent material destruction but is not establish yet, though there is a possibility that the coastal concrete structures will be destroyed by waves or tsunami. In this study, we proposed a simple method to design structure for impulsive wave pressure and confirmed the validity of this method by large flume experiments. A simple evaluation of impact response in a single mass system problem was applied. The ratio of duration time and natural period determines whether to examine by impulse damage or dynamic expansion. In the latter case, Mstatic times Lmax is compared with the bending strength. By this method, we can evaluate simply without dynamic analysis.
