DESIGN CONSIDERATION ON TRANSVERSE STRENGTH OF CONTAINER SHIPS

In previous papers, the torsional strength and rigidity of container ships was reported, but described in this paper is the transverse strength of the hull which is one of the more serious problems of containerships with long and wide hatch openings. To examine the transverse strength, the double bottom and side structure were substituted by an unfolded plane structure and analyzed using a computer. 1) The ballast condition is the severest among several loading conditions. 2) Where the double hull changes to the single hull in the middle of the hold, the stress is higher in this area. 3) When a deep floor equal to the height of a container was fitted, the shear force of the floor and the bending moment of the center girder decreased by about 20 and 10 percent, respectively. 4) The value of the mutual friction between containers and between a container and the ships bottom has no direct effect on the stress of the floor and the girders that were being considered here. 5) The shear force on the double hull part and the axial stress on the transverse box girder were not so large as to cause a problem.
