WebThe Euler buckling load can then be calculated as F = (4) π2 (69 109 Pa) (241 10-8 m4) / (5 m)2 = 262594 N = 263 kN Slenderness Ratio The term "L/r" is known as the slenderness ratio. L is the length of the column and … Euler's critical load is the compressive load at which a slender column will suddenly bend or buckle. It is given by the formula: where • , Euler's critical load (longitudinal compression load on column), • , Young's modulus of the column material,

WebDec 21, 2024 · Weighing up all of these things means the only way to accurately determine the effect length factor K for determining the axial capacity is to do a buckling analysis to get the buckling load and then use this to determine the design capacity in accordance with your design standard. Don't guess, you'll be wrong.
