THREE-DIMENSIONAL RELIABILITY RESEARCH OF OVERALL STRUCTURE FOR SEMI-SUBMERSIBLE OFFSHORE PLATFORMS

In this paper, the reduced stiffness matrices and the equivalent nodal forces of a three-dimensional frame at the plastic stage are deduced and a general programme to analyze the reliability of two- and three-dimensional structures is developed using a three- dimensional frame structural system to model or to idealize the semi- submersible platform. The branch-and-bound method is also improved significantly. Structural system reliability analyses are carried out through a calculated example, which verify the reliability and the generality of the proposed method and the programme.
