This paper deals with the ยฎnite element formulation for the analysis of space frames. A numerical method is presented to take into account the deformation of the joint connections in linear, non-linear and stability analyses of three-dimensional thin-walled beam structures.

A so-called exact static stiffness matrix for a uniform beam element with open thin-walled cross-section carrying an axial compressive load is derived. This stiffness matrix is useful in an accurate calculation of bifurcation loads and corresponding buckling modes of space frames built up of such be
