Axial Load Capacities for Single Plates: Based on Gross Section Loaded Uniformly in Either Tension or Compression per AISC 9th Edition Manual (ASD)

Compression (buckling) capacity of Plate: Rc = Fa*Ap

where:

Ap = Hp*tp

r = tp/(SQRT(12)) (radius of gyration for minor axis of plate)
KL/r = K*Lc/r (slenderness ratio)
Cc = SQRT(2*p^2*29000/Fy)
If KL/r <= Cc then Fa = (1-(K*Lc/r )^2/(2*Cc^2))*Fy/(5/3+3*(K*Lc/r)/(8*Cc)-(K*Lc/r)^3/(8*Cc^3))
If KL/r > Cc then Fa = 12*p^2*29000/(23*(K*Lc/r)^2)

Fy = yield stress

Lc = unbraced length for compressive buckling
K = effective length factor for compression
