Steel Angle Design
Tension, compression and flexural capacity of single (L) and double (2L) hot-rolled angles per AISC 360-16 (LRFD). Pick a shape and grade, set the connection, effective lengths and demands, and read every limit-state resistance, utilisation and governing clause — including single-angle E5 effective slenderness and F10 flexure about the principal axes. Imperial units (kips, ksi, in).
Tension D2(a)
| φt·Pn yield (D2a) | 121.5 k | |
| φt·Pn rupture (D2b) | 125.2 k | U = 0.869 |
| Governing φt·Pn | 121.5 k | Yielding |
Check block shear (J4.3) separately — it can govern at the connection.
Compression E5-1/E5-2
| (Lc/r)eff | 132 | E5-1/E5-2 |
| Fcr | 14.5 ksi | |
| φc·Pn | 48.9 k | φc = 0.90 |
| Demand Pu | 40.0 k |
Flexure F10.2/F10.3
| Yield-limit Mn | 8.8 k·ft | |
| Mcr (LTB) | 64.5 k·ft | |
| φb·Mn | 6.4 k·ft | LTB |
| Demand Mu | 2.0 k·ft |
Section properties L

AISC 360-16 (LRFD). Single (L) and double (2L) hot-rolled angles. Single-angle compression uses the E5 effective-slenderness method (angles connected through one leg); double-angle compression uses E3 (x) + E4 flexural-torsional (y) with E6 built-up modification. Block shear (J4.3) at connections and H2 biaxial interaction are not included — check separately. Verify connection eccentricity, bracing and load combinations independently. A licensed P.E. review remains required.
