EFFECTIVE AREA OF RING STIFFENERS FOR AXIALLY SYMMETRIC SHELLS

摘要

The effectiveness of T- and I—section ring stiffeners in axially symmetric shells undergoing axially symmetric deformations is examined under the assumption that the thicknesses of the shell and flanges and web of the stiffeners are small compared to the other dimensions. Curves are presented for obtaining the effective area and the flange stress of T-stiffeners. Approximate formulas for stiffeners with depth of stiffened small compared to the radius of the shell arc also' presented.
