This paper explains how to calculate the correction factor for keel inertia moment due to the dead rise of grillage and how to consider bulkhead plating in calculation of dock strut response to keel cribbing. The solutions described in this study are different from the commonly used ones. New formulas have been obtained for taking into account inertia moment of grillages with dead rise, as well as for calculation of Euler stresses in dock struts, and their design algorithm has also been updated. The results offer more accurate calculations of grillages with dead rises and more accurate design of transverse bulkheads in terms of conventional beam models and methods of structural mechanics.
