heal.abstract	This study deals with the stability analysis of elastic framed structures, free from imperfections, which are acted upon by concentrated joint loads. Attention is focused on the conditions under which primary bending is ruled out then the above analysis leads to a classical eigenvalue problem from which one can establish critical buckling loads and corresponding buckling modes. To this end by using simple frames as models the individual and coupling effect of various parameters (e.g. geometric imperfections, elastic supports, etc.) for which these structures may exhibit a trivial fundamental equilibrium path (from the onset of loading up to its critical value) are thoroughly discussed. It is also found that in case of non-existence of primary bending the components of the joint loads in the directions of the bars of the joints, coincide with the corresponding axial (internal) forces. © 1997 Elsevier Science Ltd.
