Abstract
The target of the present study is to investigate the buckling stress of a member representative of a rigidly jointed single-layer reticular dome. The buckling stress and the normalized slenderness ratio have been derived from elastic plastic buckling analysis and the elastic buckling stress by linear eigenvalue analysis, respectively. The results of the elastic plastic buckling analyses are summarized to evaluate the ultimate strength of the reticular dome as a function of the normalized slenderness ratio. According to several numerical analyses, it is confirmed that the proposed design procedure gives an accurate estimation on the buckling collapse of reticular domes.
