Toward an Integrated Design, Inspection and Redundancy Research Program

摘要

The Loads Advisory Group of the Committee on Marine Structures recognized in October 1981 that the emerging technologies of ultimate strength and failure mode analysis have indicated a relationship among design-inspection-redundancy practices not heretofore fully appreciated. This report contains the elements toward integrated design, inspection, and redundancy marine structure research programs where the descriptions are only in sufficient detail to serve as a guide for further development by the established mechanisms of the interagency Ship Structure Committee. The studies outlined are of long-term development and synthesis of existing information as well as deterministic/probabilistic information yet to be acquired. They are based on the results of a three-day symposium program and a two-day workshop organized and held to examine the emerging technologies of ultimate strength and failure mode analysis. While relatively reasonable computations of structural systems in the elastic range, and approximate estimates of some modes of maximum, ultimate strength can be made, the ability to detect degrees of damage and to assess the margin of strengths is limited at best. A great deal of deterministic (experimental and analytical) work is yet to be done to arrive at a satisfactory predictive position of practical usefulness.
