1.054/1.541 Mechanics and Design of Concrete Structures Spring 2004 Prof. Oral Buyukozturk 1 / 2 1.054/1.541 Mechanics and Design of Concrete Structures (3-0-9) Homework #1 Assigned: Thursday, February 12, 2004 Due: Tuesday, February 24, 2004 Design of A Concrete Gravity Platform This problem is about failure criteria for concrete in a variety of stress states. An application considered in this problem is the concrete gravity platform (offshore structure). A brief introduction is first presented followed by questions on the behavior of concrete in this application. Introduction A concrete gravity platform is one that is placed on the seabed, and by its own weight, is capable of withstanding the environmental forces (wind and waves) it may be exposed to during its lifetime. Gravity-type concrete platforms are used for oil-drilling purpose in the oil industry. They are used when the soil/rock of the seabed is hard and relevant for supporting them since they rest directly on the ocean floor without pile foundation. Concrete platforms are larger and heavier than steel platforms. Although there are various designs of a concrete gravity platform, the base part is usually made of reinforced concrete and consisted of huge sub sea concrete tanks.
