curved columns
(OP)
I need to design a curved column to be supporting a eccentric load.
any help in the calculations and best formulas to use in working the max force and stress it can take
cheers

RE: curved columns
i don't think this is like the standard "euler" column analysis, where a straight column snaps through; i think this is more like critical stress = yield stress. ie, the beam is initially curved and the loading only increases the curvature.

RE: curved columns
1) This is an example where AISC's Direct Analysis method will really help. The stiffness reductions included in the DA Method are intended to capture the INelastic buckling whereas a pure P-Delta analysis would only capture the elastic buckling.
2) If the column is curved only in one direction, you will probably want to apply a notional load in the other direction. Because, a small eccentricity could cause some de-stabilizing torsion in the cross section that you would want to be taken into account for the P-Delta analysis.
