5 Conclusions

A series of element tests using Cyclic Simple Shear (DSS) Apparatus has been carried out to find out the change in shear modulus of the soil under different conditions of cyclic loading. The loading pertained to the particular scenario of offshore wind turbines. The results obtained from the element tests reinforced the observations from the scaled model tests and DEM analysis thereby boosting our confidence in the understanding of the physical mechanism and processes controlling the long-term behaviour of these new structures. While scaled model tests can be insightful to understand the physical mechanisms, the scalability of the results to real application is difficult if the same soil is not used for the model tests. In such cases, element tests provide a better alternative. This paper shows element tests that may be helpful to predict the long-term performance.
