D1.B.1.1.3 Stress Due To Compression
Allowable compressive stress on the gross section of axially loaded compression members is calculated based on the formula E-1 in the AISC Code, when the largest effective slenderness ratio (Kl/r) is less than Cc . If Kl/r exceeds Cc , allowable compressive stress is decreased as per formula 1E2-2 of the Code.
