There is strong indication these days that the idea of plastic design will be applied to the determination of hull structure. Also, in this shipyard, we have been making examinations for application of the idea of plastic design to some parts of hull construction members, and reports on the matter have been made at some meetings. This paper deals with the results of these investigations. The following are the conclusions of the investigations. (1) Shape factor of bar with plate is 1.4-1.5. (2) Effect of axial force upon plastic modulus of bar with plate is small. (3) There is an extreme unbalance between collapse loads of bottom longitudinal frames, deck girders, beams and pillars. It is very important in designing hull construction with the idea of plastic design to determine safety factor and allowable deformation of construction members under the fixed safety factor. However, this matter will be taken up for investigation in the future.
