heal.abstract	In this paper, a simplified but very reliable approach for the nonlinear buckling analysis of frames subjected to either bifurcational or limit-point instability is proposed. This approach, based on slightly modified kinematic continuity conditions, is demonstrated through the buckling analysis of a simple two-bar frame. Numerical solutions, obtained by an accurate nonlinear buckling analysis and two simplifying variants of it, are established for a wide range of values of several parameters. Comparisons of these solutions show the simplicity, speed, and reliability of the buckling approach proposed herein. Moreover, a simple stability criterion is established for a direct determination of critical loads.	en
