A DESIGN PROCEDURE FOR DETERMINING THE CONTRIBUTION OF DECKHOUSES TO THE LONGITUDINAL STRENGTH OF SHIPS

Abstract

A design procedure for determining the stresses in deckhouses is presented. The method includes a tabular procedure for calculating an effective moment of inertia which reflects the effectiveness of the deckhouse in contributing to longitudinal strength. The theoretical approach utilizes semi- empirical results of full scale experiments to evaluate the effect of differential deflections between deckhouses and their parent hull girders. This data was incorporated into an analytical treatment of the problem based on the plane stress theory. It is shown that all deckhouses contribute somewhat to the strength of ships and that this fact is useful to the naval architect in his quest for a structurally efficient ship.
