Two-Beam Deckhouse Theory with Shear Effects
Abstract
The paper deals with the structural response in vertical bending and shear, of the upright ship hull with a deckhouse. The basis for the analysis is that of considering each component as a thin-walled Navier beam and accounting for (a) vertical loading of the deckhouse by a foundation modulus 'k' in the usual manner; (b) vertical shear deflection of each component in addition to bending deflection; (c) non-equality of longitudinal strain at deckedge and deckhouse connection by applying shear lag theory to the deck. The superstructure is handled as a special case, with only (b) above being applicable. Design charts are presented, based on the solution to the differential equation, for computing (1) longitudinal stresses at midlength, (2) shear flow at bond, and (3) differential deflection of the two components. It is indicated that the three items (a), (b) and (c) may be of the same order of importance. A few preliminary experimental results are included.
