The purpose of this paper is to examine the elasto-plastic buckling behaviours of a rigidly jointed single layer reticulated dome to a static load applied at its centre. The numerical formulation is based on the incremental finite element method incorporating geometric and material nonlinearities. The buckling behaviour is investigated in regard to the shell geometry, the member property and the material property. The nonlinear buckling load and the deformation of the dome are discussed based on parametric study.
