BASIC DESIGN CRITERIA ON THE STRENGTH OF SHIP STRUCTURES
This paper presents a basic concept of structural design which assures the safety and durability of ship structures by establishing a rational design criterion based upon reliability analysis and empirical data obtained from operational experience. The first step involved a statistical estimation of extreme loads and structural responses occurring during the ship's lifespan. Measurements of longitudinal stress taken on a container ship in the seaway confirms this analysis. Reliability analysis on structural failure due to yielding, buckling and total collapse, and due to fatigue cracks in welded joints is made. Design criteria are proposed to determine a set of allowable stress components for the structural members of ships based upon failure probability for either yielding or fatigue crack initiation.
