Single Angle — Compression (E5) and Flexure (F10), AISC 360-22

Enter section properties from AISC Manual Table 1-7 (the free AISC Shapes Database). Compression uses the E5 effective slenderness when its five conditions are met; flexure covers geometric-axis bending of equal-leg angles and principal-axis bending.

AISC 360-22E5 (E5-1 to E5-4), E3, E7, E4 note; F10 (F10-1 to F10-8, F10-5a/b, ×1.25 with restraint at maximum moment); Tables B4.1a case 3, B4.1b case 12. Unchanged from 360-16.

VerifiedAISC Companion V16.0 Vol. 1 Examples E.14A, F.11A, F.11B and F.11C reproduced. E5(a)(2) (planar truss, unequal-leg angle connected through the shorter leg) is not implemented — its coefficient could not be read from the primary text available.
