To establish a reliable tsunami-resistant design for building that require a high degree of safety and robustness against tsunami, a quantitative evaluation of dynamic behavior of run-up tsunami and resulting tsunami loads is essential. In this research, we performed numerical simulations of hydraulic bore flow with an elastic plate to fundamentally investigate characteristics of wave impact loads acting on a deformable structure. For the numerical simulations, we apply fluid-structure interaction analyses based on the coupled SPH and FEM. The numerical simulation results suggest that impulsive wave loads under bore can be reduced depending on deformation capacity of structure.
OMURA et al. (2025) studied this question.
