Abstract
When solving frame stability problems, replacing a distributed load acting on a frame element with an equivalent load in the form of concentrated forces that are applied in the frame nodes is often resorted to. This causes the bending equilibrium of the beam to become a non-bending tension-compression equilibrium. The buckling load for such frames can be either greater or less than the actual load.
