Stress Analysis of Openings (Slots) for Longitudinals in Ship Structures by Finite Element Method

概要

Generally slots are cut into the transverse webs for the passage of secondary members (longitudinal) in ship structures. The present structural design of the slot part makes it too complex and at times strengthened above the required safety levels of hull structure. A zoom analysis of the global model can be carried out to find the possibility of simple slot structure design. This study is a structural analysis of a typical Bulk Carrier by FEM zoomed to the slot part under two selected loading conditions. The rigidity of the longitudinal and the importance of collar plate and web stiffeners are analyzed with different scantlings. Then the shape of slots and its effect on the stress distribution around this particular region are used to find out the possibility of a slot design without collar plates and web stiffeners.
