| Condition | Effective Section | Yielding |
|---|---|---|
| [Diagram] | Aeb = Betb | Tension or Compression Yielding Rn = FybAeb (Punching) Shear Yielding Rn = 0.6Fyt(2tb + 2Bep) |
| [Diagram] - Not present for T- or Y-connection | Aeb = (Be + Hb⁄Bb + Hb) Ab | Tension or Compression Yielding Rn = FybAeb (Punching) Shear Yielding Rn = 0.6Fyt(2Hb + 2Bep) |
| Branch(es) under In-Plane Bending T- and Cross-Connections [Diagram] - Not present for T-connection | Zeb = Zb (1 - Be⁄Bb) BbHbtb | Tension or Compression Yielding Mn = FybZeb (Punching) Shear Yielding Mn = 0.6Fyt x (2tb + Hb) (Hb⁄2) |
| Branch(es) under Out-of-Plane Bending T- and Cross-Connections [Diagram] | Zeb = Zb - 0.5 (1 - Be⁄Bb)2 Bb2tb | Tension or Compression Yielding Mn = FybZeb (Punching) Shear Yielding Mn = 0.6Fyt(2tb + 2Hb) x (Bb - tb) |
