The critical load is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the column will deflect laterally. The critical load puts the column in a state of unstable equilibrium. A load beyond the critical load causes the column to fail by buckling. As the load is increased beyond the ...

The resulting flitched beam was then secured with resin and bolts, preserving appearance while providing strength. Flitch beams were used as columns in a two-story new construction.
