Welded Web Connection (WUF-W Moment Connection)
Welded web connection is designed automatically according to the AISC 358-16 by the programme.
The connection model in accordance with AISC 358-16 Figure 8.2 is made automatically.
Ductile failure limit state (Yield Limit State):
Non-ductile failure limit state (Rupture Limit State):
Plastic joint length Sh is defined in the relevant application rules section for each joint type.
Plastic joint moment values:
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.
The value of Ze shall be taken as equal to Zx of the beam section and the value of Cpr is taken as equal to 1.4.
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.
Beam depth is limited to a maximum of W36 (W920) for rolled shapes
Beam flange thickness is limited to a maximum of 1 in. (25 mm)
The clear span-to-depth ratio of the beam is limited:
(a) For SMF systems, 7 or greater
(b) For IMF systems, 5 or greater
The protected zone consists of the portion of beam between the face of the column and a distance one beam depth, d, from the face of the column
The beam is connected to the flange of the column
Rolled shape column depth is limited to a maximum of W36 (W920)
