Abstract
Grillages consisting of intersecting beams are supporting shell structures of the ships in different places such as bottom, deck and sides. Different methods available for strength analysis of plated grillages are studied from the viewpoints of characteristics and limitations. Finally, the way to assess the strength of such structural elements is investigated. This study is based on preparation of a soft-ware for analysing the grillages. Using the software, it is possible to analyse grillages used in the ships’ structures for any type of boundary and loading conditions that are simply selectable by users. Getting the required input data from the user, elastic deflections and stresses induced as a result of applying concentrated or distributed loads are calculated at the intersections of the longitudinal and transverse members, relieving the need to complicated numerical calculations.
