Web, column effective length factor; This formula was derived in 1757 by the Swiss mathematician Leonhard Euler. The column will remain straight for loads less than the critical load. 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. Webthat buckling will take place non-elastically. In this paper, a methodology is proposed to calculate plasticity reduction factors for flat Glare plates either loaded in compression …
