Abstract
The present paper investigates both the elastic and elastic plastic dimple buckling behaviors of a rigidly jointed latticed dome of single layer on a hexagonal plan. The calculation is performed changing several parameters; the number n of grid along line through the apex, the angle θ_0 of the central member at the apex, and the type of boundary conditions. Those buckling loads are expressed in non-dimensionalized form by classical linear buckling load of continuous isotropic spherical shell. And the present study also has revealed that modified Dunkerley's formula is effective to predict the elastic plastic buckling load of the present latticed dome.
