Nettet2.3.1.7 Bending Failure of Eccentrically Loaded Long Columns. A theoretically correct formula that holds for eccentrically loaded columns is the secant formula : P A = Fcol 1 + ec ρ2sec[L 2ρ√ P AE] (2-3) In this formula, P, A, ρ, L, C, and E are defined as before, and e is the eccentricity of the load. NettetFrom the Euler buckling formula for a perfectly elastic column (N euler = π 2 EI/l e 2), the capacity of a long column to resist flexural buckling under compression alone is primarily a function of its elastic stiffness (EI) and interaction with yielding.
