| Abstract: |
Grouted connection (GC) is an important part of the offshore wind turbine (OWT) support structure. There are a lot of axial compression tests of GCs. But in order to thoroughly study the effects of different parameters on GCs, it is necessary to carry out the numerical study with the finite element method (FEM). In this study, the local models of GC were established by using the FE software ABAQUS. The numerical results were verified by the experimental results. A parametric study was carried out to investigate the influence of grout thickness, lateral compressive stress, shear key spacing, and the number of shear keys. The study shows that increasing the lateral pressure and the number of shear keys can significantly improve the bearing capacity. While increasing the grout thickness within a certain range will reduce the bearing capacity. And increasing the shear key spacing within a certain range will improve the bearing capacity. |
