Use for


Situation	Description
	Shear tab is welded to the column and bolted to the beam.

Limitations

The column must be either an I section or a tee section. For tee sections, the beams are connected to the flanges of the tee to create a section in the form of a cross.
Beams must be I sections.
Beams can be horizontally skewed up to a limit of 5 degrees.
Beams cannot be vertically sloped.

Selection order

Select the main part (column).
Select the first secondary part (beam).
If needed, select the second secondary part (beam).
Click the middle mouse button to create the connection.
