Pinned-Pinned
K = 1.0
Slenderness Ratio (AISC 360-22 E3)
KL/r = (1.0 × 168 in) / 2.51 in = 66.9
4.71√(E/Fy) = 4.71√(29000/50) = 113.4
Since KL/r < 4.71√(E/Fy), use Equation E3-2
Compression Capacity
Fcr = [0.658(Fy/Fe)] Fy = 39.2 ksi
Pn = Fcr × Ag = 39.2 ksi × 17.0 in² = 666 kips
φcPn = 0.90 × 666 kips = 599 kips
Pu/φcPn = 350/599 = 0.58 ✓ OK
