Situation	Description
	Brace profile: RHS Framing type: Column and extended end plate Gusset plate is welded to an extended end plate. Braces are bolted to the gusset plate using tongue plates.
	Brace profile: RHS Framing type: Column and beam Gusset plate is welded to the column flange. Braces are bolted to the gusset plate using tongue plates, and connection and cover plates.

Before you start

Create two parts that form a corner, and 1 to 10 braces.

Selection order

Select the main part (the first part that forms the corner).
Select the secondary part (first brace).
Select the second secondary part (second brace).
Select the subsequent secondary parts (subsequent braces).
Select the secondary part that forms the corner (Tekla Structures connects the gusset plate to this part).
Click the middle mouse button to create the connection.

Note:

Tekla Structures uses values in the joints.def file to create this component.
