Basics
Ductile failure limit state (Yielding Limit State):
...
The Vu used in the dimensioning of the joint is determined according to the equation in the above image by summing the shear force determined on the basis of the yield state and the shear force calculated from the combination of 1.2G + 0.5Q + 0.2S on the plastic joint at the end of the beam.
Plastic joint length is specified separately for each joint in AISC 358-16 and automatic calculation is made in accordance with these rules. Details will be given in each respective combination.
