Sorted by: 1. λ 1 is the minimum slenderness ratio at which buckling will be the dominant condition for a purely axially loaded element. Interestingly, it is an intrinsic property of the material, not the geometry. It's derivation is simple: P c r i t = π 2 E I L 2 P c r i t A = π 2 E ⋅ I L 2 A σ c r i t = π 2 E ⋅ i 2 L 2 σ ... WebAug 28, 2008 · The moment becomes approximately 13.7*11.8^2/8 = 239inlb. Using my previously calculated moment of inertia, this gives a stress due to local bending of 0.7ksi - much more manageable. Add to this a local axial stress on our strip of 13.7*10/2/(1*1/2) = 0.14ksi and I don't think you'll have any local beam-column buckling of the wall. ibond best time to buy
