In this paper, various methods of determining of wave loads acting offshore structures including impact load due to breaking wave are studied and corresponding model test was performed. In the theoretical approach, wave load by nonbreaking wave and impact load by breaking wave is determined by Morrison's equation, Goda's equation and impact wave equation. In the experimental approach, wave load by nonbreaking wave acting on cylindrical pile used in offshore structures is determined by measuring the strain on a cylindrical pile and compared with theoretical value. In the numerical approach, impact load by breaking wave acting on a modeled cylindrical pile is calculated by using ANSYS, FEM program and compared with theoretical value. It is found that the experimental and numerical results are comparable to theoretical results. Thus, the determination of wave load acting on offshore structures can be obtained by a proposed method and it is acceptable.
