Abstract
Two corrugated and one plane bulkhead subject to a distributed lateral load were tested and most of the results are given and discussed. An extension of the beam model, as briefly dealt with earlier [1] is introduced generally and verified for certain cases. The assumption underlying the method of calculating the transverse bending moments and stresses in corrugated panels is verified with the aid of experimental data gathered both in the Laboratory itself and from previous papers by other authors. As a result a suggestion is made regarding the limitations imposed on the validity of this hypothesis by the aspect ratios and flexural rigidity ratios of corrugated panels. Transverse bending moment curves, obtained both experimentally and theoretically, are compared and for corrugated panels the possible influence of initial unfairness is discussed.
The end connections of bulkhead panels are examined in more detail. Attention is paid to the importance of tests on full scale structures subject to static loads which restrict the nominal stresses to the elastic range.
The corrugated bulkheads are compared with the plane one and finally a number of conclusions is presented.
