| Abstract: | This paper analyzes the cause of superstructure stress concentration of a flat-bottom ship with shallow draft. It optimizes the connection structure between superstructure front bulkhead and main deck by the hull strength analysis using FEM numerical calculation method Checked by real ship, this method is useful to improve the safety of the ship structure. |
