Book 2009ok presents the fundamentals, the theory and the application of structural design of hulls. The topics are treated comprehensively with an emphasis on how to achieve reliable and efficient ship structures. The authors have in particular introduced their experiences with the rapid increase of ship si

Philosophy of Hull Structure Designmically, to be a very important part of the shipyard management, since the strength of a ship is concern and the cost of the hull steel is about 20% of total ship’s cost. Therefore, a good executive needs many talented designers to assist especially in hull structure design.

Structural Design Loadssses. The structural designer needs to know the hull structure load features, as accurately as possible: direction of the working load, frequency of occurrence, distribution pattern on the hull structure and behavior in the time domain, etc. The first design step is to assume exact loads acting on t

Intercept

Strength Evaluation hull structure has been planned originally by the designer in such a way that the structure can effectively resist the presumed maximum load, which is estimated from previous experience of failure modes of damage. Therefore, once damage occurs in the structure, it indicates the following facts:

Design of Beamsendure the lateral forces such as water pressure as well as in-plane loads. When the forces are imposed, the stress distribution in the plates and the stiffeners is complex as shown in Fig. 1.1.1. The longitudinal stress in the attached plate will be a maximum at the connection line to the stiffener

Design of Girders bending moment. In the design of mammoth tankers, 40,000–50,000 DWT, built around 1960, girders were designed based only on bending theory. For the bigger ships built after that era, shearing theory has been also applied.

Design of Pillarslar is a very effectivestructural member, for example 40 cm. sectional area of mild steel can support 1000 kN force (σ = 250MPa). Considering that the pillar sometimes supports tension, attention should be paid to the connection at both ends of the pillar.
