In this paper, based on the analytical method developed in the previous paper, the general buckling (symmetric buckling or antisymmetric bifurcation buckling with respect to the longitudinal center line) behaviours of C.R.S.R. with simply supported ends, subjected to external pressure, were studied numerically introducing Classical Buckling Pressure (the critical hydrostatic pressure of the full Reticulated Cylindrical Shells), under various (1) reticular parameters, (2) generator edges, (3) shell geometries. In the §2, the author investigated the general buckling behaviours of C.R.S.R. in the range of (1) γ=ζ=0.5, α=60°, that to say isotropic, (2) pinned, simply supported, free edges, (3) μ_h=100〜300, β=1, 1/1.5, 0.5. In the §3, the author investigated the general buckling of three types of orthotropic C.R.S.R. In the §4, the analytical values were compared with experimental values in the case of isotropic with free, fixed genera-tor edges.
