A Study on the Worst Load Point in Grillages

초록

Grillage is common types of structures in marine and land-based structural system. Grillage system that increases the stiffness of plate used by two rectangular across stiffeners is a part of deck, side shell and bottom. The worst load point of those structures is dependent of the loads, which are lateral, in plane or combination of those directions as well as boundary conditions. The worst deflection point is produced when the point load is examined at central intersection. But the worst loading point would not necessarily be at the central point. The main objective of this paper is to find the maximum stress point in grillage system. Bending and shear stress is considered while load applied at a point. To perform this study, direct stiffness method is used as analysis tool. Also the variation of section and length of beams that are an element of grillage system, investigate the effect of changes.
