دانلود کتاب Design Guides for Offshore Structures, Volume 1 - Welded Tubular Joints

From the practical standpoint, this Guide represents the culmination of the research program on fatigue in welded steel offshore structures initiated in late 1976. These researches are conducted as part of a French national research program. The first phase of this work was intended to improved knowledge about the fatigue behavior of welded tubular joints subjected to random loads due to natural elements (wave, wind, current). It comprises two complementary parts, one theoretical and the second experimental. The present Design Guide offers a summary of design methods and knowledge about the design and analysis of welded tubular joints for the construction of offshore petroleum structures built of steel. The objective led its authors to go beyond the strict framework of the problems raised within the “European Program on Fatigue in Welded Offshore Structures” to deal with other problems likely to influence the dimensioning of a joint, or to affect the fatigue strength of a welded joint.
