Abstract: An approximate analytical method of estimating effective breadth of deck plating is presented. The deck plating in the region of 0.4L amidships is considered, as subjected to linearly distributed line loads along the edges of the deck plating and in way of the longitudinal bulkheads, together with longitudinal normal forces at the ends of 0.4L region. It is assumed that the contraction of the deck plating is small (not neglected). Analytical solutions are obtained for the stress distribution in the deck plating of ships without longitudinal bulkheads, for ships with a central longitudinal bulkhead and also for two symmetrically located longitudinal bulkheads. The method is applicable for ships without cargo hatch openings only, as tankers. The results are checked by the finite element method.
