A conventional method of analysis and design for trough-shaped bunkers is explained. A full-scale test on a large coal bunker is described and the experimental coal pressures and the stresses in the steelwork are compared with design values. Further measurements from a similar model in aluminium are reported. It is shown that theoretical strcsses can be brought into line with measured stresses if the plating is assumed to act with the stringers and, to some extent, with the main and the base girders; such assumed composite action might well be the basis for future design recommendations.

The loading and structural behaviour of ships are described in general terms and an account is given of some of the contributions to structural knowledge which have emanated from shipbuilding sources. Design policy is discussed and it is noted that the design rules of the classification societies, which are based primarily on experience rather than on explicit factors against limiting conditions, lead to structures which are economical and safe. The classification societies (the largest of which is Lloyds Register) retain responsibility for the ship’s structure throughout its life; the experience on which the rules are based is therefore extensive and well co-ordinated.

The design of submerged tunnels is a very wide subject and this paper, therefore, gives only an outline of the problems encountered. Aage Brink
