In this paper, the behaviour and the strength of simply supported plates (aspect ratio α=1,2 and α=∞ (infinitely long plates) having in-plane constraint in the transverse direction under combined loads of compression and hydrostatic pressure are theoretically investigated following the previous studies. At the same time, effects of aspect ratio of plates on the behaviour and the strength are also discussed from these results including those for plates of α=3 and 4. Results obtained in this study are summarized as follows: 1) Carrying out the analyses based on equations deduced to pursue the elastic behaviour of plates (α=1,2 and ∞) whose long sides are transversely immovable (ey=0), characteristics of behaviours including buckling phenomena are clarified. 2) The compressive strength of such a plate is calculated in the same way as the previous paper, and characteristics of the compressive strength and the collapse mode of the plates (α=1,2 and ∞) are clarified. 3) From comparison between above results including those for plates of α=3 and 4 and results for the case of plates having no in-plane constraint (Py=0) in the previous paper, it is found that the behaviour of the plate for each case is different but the effects of aspect ratio of the plate on the changes of the buckling and the compressive strengths with hydrostatic pressure for each case are generally similar.
