The main aim of this paper is to present several "elastic buckling loads" of uniformly pressurized perfect and imperfect spherical caps in relation to slenderness parameters. "Elastic buckling loads", in this paper, mean R. S.(Reduced Stiffness ) load, asymmetric bifurcation load, upper buckling load with and without initial imperfections, Astatic buckling load and so on. Through parametric studies, the buckling characteristics are also illustrated. Numerical results are normalized and plotted against three slenderness parameters derived from : classical buckling stress; linear buckling stress; and equivalent stress, respectively. A comparison is made, in view of buckling stresses, with the values given by buckling strength curves in the codes and with past experimental results.
