Foundations for offshore wind turbines are predominantly demanding due to the dynamic nature of the offshore loading. A greater understanding of the behaviour of wind turbine foundation soil, will certainly lead to the stable construction of foundations which in turn, will make offshore wind farms a more feasible part of the solution to the global energy problem. This paper presents the results of cyclic direct simple shear test to explain the long term cyclic behavior of marine silty sand. All the tests are performed with relative density of 65% and 70%.Cyclic behavior of marine silty sand are based on the number of loading cycles, cyclic shear strain amplitude, relative density, and cyclic stress ratio.
