In this note the error in the computation of the elastic critical load of columns and rigid-jointed plane frameworks by the finite element method, as developed in general by Gallagher and Padlog and applied to frameworks by Hartz is determined. This error is computed on the basis of a comparison of the finite element method with the exact stability stiffness matrix method as described.
