ABSTRACT:
An earthquake-resistant off-shore gravity structure which can stand on the sea bed under its own weight and the weight of any ballast carried by the structure has coupled to its undersurface a separately formed substantially flat concrete foundation grid which underlies at least a major part of the area of the undersurface of the structure, which is of a thickness substantially less than the height of the base and which has a downwardly extending projection for penetrating the sea bed. The coupling between the structure and the foundation grid is such that vertical loads on the structure are transferred through the foundation grid to the sea bed and is such that, for horizontal forces on the structure less than a predetermined maximum value, relative movement between the foundation grid and the structure is substantially prevented and, for a horizontal force equal to or in excess of said maximum value, limited relative movement between the foundation grid and the structure is permitted. Preferably, when the structure is subjected to a horizontal force of gradually increasing value, as may occur in the event of an earth tremor, when the value of the horizontal force reaches said predetermined maximum value, limited relative movement between the foundation grid and the structure is permitted without any further increase in horizontal force on the structure.
