STRUCTURAL INTERACTION BETWEEN SHIP'S HULL AND SUPERSTRUCTURE

The problem of interaction between ship's hull and superstructure is complicated by various non linear effects, such as shear lag in both hull and superstructure, deformation or slip in the connection between superstructure and upper deck and differential curvature between hull and superstructure due to the flexibility of the upper deck. These effects are not usually considered in conventional strength calculations. This paper gives a method for calculating deflections and stresses in the hull and superstructure taking account of all various factors influencing the deckhouse and superstructure characteristics. The problem is discussed in a general way and presented in simple stiffness concept form as the finite strip method being applied with certain assumptions. The paper also includes a study on the object of superstructures and deckhouses effective breadth and efficiency and how it contributes to the longitudinal strength of ships.
