Abstract:

An infinitesimal theory of instability of an elastic orthotropic shell of revolution subjected to uniform external normal pressure is developed. The theory leads to a linear eigenvalue problem for determination of the buckling pressure. Illustrative numerical calculations based on piecewise-polynomial approximations and the partition method are given for the Fort Martin tower erected in West Virginia by the Marley Co. The tower is a reinforced concrete hyperboloidal shell of revolution, 370 ft. high and 5.5 in. thick for most of its height.
