Full color, richly illustrated book. This manual aims to gather and disseminate the modern OSD technology based on worldwide practice. Emphasis is now placed on the fact that the design of these structures is generally controlled by fatigue limit states. Details necessary to make these structures work require advanced fatigue evaluation techniques that must rest on accurate stress range calculations, which is possible with the use of the Finite Element Analysis (FEA) and/or prototype testing. The fatigue testing database has grown considerably over the last few decades, which has provided the necessary data for proper evaluation and detailing for fatigue resistance.
