A connection formed under water between a wind turbine tower and a wind turbine foundation. Mounted to the column 2 are brackets 6 which pass around posts 7 which are connected to a base member 3 comprising foundation 4. Enlarging members 8 are connected by swaged, crimped, pegged, wedged or other joints to the posts 7. For pre-loading, jacking members 10 or flanges 110 are operated to load the enlarging member 8 or flange 101 and spreader member 11 bearing on brackets 6 and column 2 with compression force and post 7 with same tension force to connect column 2 to base 3. A plinth extends from the base 3 into the column 2 forming a horizontal shear connection. The combined actions of tension in posts 7 and compression on base 3 and the shear plinth rigidly connect the tower to the foundation. Brackets 6 also increase the columns stiffness, which reduces horizontal deflections of tower. |
