Experimental study of irregular wave impact on structures in the splash zone

Abstract The experimental investigation of irregular wave slamming on structure members with large dimension in the splash zone is presented. The time-domain and frequency-domain analyses results of the irregular wave impact pressure on the subface of the structure under various case studies are presented. The influence of different incident wave parameters and relative clearance s / H 1/3 on the impact pressure is discussed. The empirical formula of the characteristic impact pressure P c , P t and the spectral moment of the impact pressure m 0 on the structure are proposed. The empirical expression of the characteristic peak impact pressure P c and the spectral moment of the impact pressure m 0 on the structure is given.
