The Effect of TLCD and TMD on Floating Breakwaters Against Waves

Four different models of floating breakwaters were investigated and numerically simulated in this study, all of which had mass and liquid column dampers. All elements of solid type were modeled in Abacus software “concrete, water, soil, damper, breakwater”. The type of analysis is dynamic and explicit, and the nonlinear effects of deformation are considered. This study compares different dampers with the damping of waves and seismic forces. The originality of this method is related to comparing the numerical results of a simulated model in Abacus and comparing it with the laboratory results of the same approved model and examining the different models and the results of the diagrams drawn from them, we conclude that if we use TLCD liquid column and TMD mass dampers as hybrids on the floating breakwater used in this paper, the greatest reduction effect on displacement and slip variables will be created for us. And the finite element method has been used for meshing different components for dynamic analysis. This article aims to obtain an optimal composition to minimize slippage and displacement in the floating breakwater article.
