Summary

A vibration analysis of waffle cylinders with various stiffener configurations is made using the energy method. The frequency factors of the stiffened cylinders are obtained in terms of various non-dimensional parameters. To make a comparative study, the frequency factors are maximised for a fixed cylinder mass and stiffener eccentricity ratio. It is observed that spiral and circumferential configurations are efficient whereas axial stiffening is detrimental.
