Abstract

To evaluate the response of floating bodies in the deep seas, it is necessary to evaluate the responses of the bodies in the Stokes waves. The fifth-order Stokes waves are expressed as a superposition of five linear waves. Therefore, the dynamic structural responses of the bodies in the Stokes waves would be expressed as a superposition of the dynamic structural responses of the bodies in each linear waves. In this research, for the elastic beam model, the structural strength of the linear and Stokes waves with the same wave height (H = 0.12 m) was calculated. By comparing and reviewing the calculation results for the linear wave and the calculation result for the Stokes wave, the characteristics of the structural response in the high-frequency region were evaluated.
