APPLICATION OF HYBRID SPHERICAL SHELLS TO HUGE FLOATING MARINE STRUCTURES

With a view to adopting a part of a spherical shell as a structural element in such structures to prevent the occurrence of tensile stresses under uniform pressure, the paper investigates such shells under uniform pressure. Generally speaking, when subjected to uniform normal pressure, the stresses caused in a part of a spherical shell are mainly compressive stresses, and bending moments appear only in the narrow region along shell end. Moreover, it is possible to eliminate almost all of tensile stresses by properly selecting the radius of a sphere, the girder spacing and the thickness of shell. Results of an experimental and analytical study are presented.
