COLLAPSE AND POST-COLLAPSE OF SHALLOW LATTICE DOMES

In this paper a numerical and experimental study of the collapse and post-collapse behaviour of shallow lattice domes is carries out. The solution of the nonlinear stiffness equations is desined so that critical points on the equilibrium path are identified in the results as well as obtaining the bifurcation path. The experimental results presented are compared with the corresponding numerical prediction and their reasonable agree-ment demonstrated.
