A FINITE ELEMENT ANALYSIS OF ECCENTRICALLY STIFFENED CIRCULAR CYLINDRICAL SHELLS,

Abstract

The objective of this study is the development of an analysis method capable of handling circular cylindrical shells that have been stiffened both in the axial (longitudinal) and circumferential (hoop) directions by beamlike members. Further, it is desired to allow these stiffeners to be placed eccentrically, that is, the centroid of the stiffener not coinciding with the shell. Seldom are they placed symmetrically because of fabrication problems and loss of efficiency of the stiffener. The eccentrically stiffened cylindrical shell represents a broad range of practical structures, including airplane fuselages, rocket casings, nuclear reactor containment vessels, and cylindrical roof shells.
