VIBRATIONS OF LARGE MARINE STRUCTURES

For this study of the hydro-elastic coupling of large offshore structures during free and forced vibrations, the Author (of the Institut Francais du Petrole) analyses the dynamic response of an elastic cylinder, of comparatively large diameter, standing vertically in the sea and subjected to severe loads from waves and earthquakes. The analysis, which takes into acccount the influence of the structure's added mass (this "modal" added mass differs from that of a rigid structure), is explained in some detail, its range of validity is examined, and a numerical example is given. A number of conclusions are drawn. Order from: BSRA as No. 48,741.
