Corner bolted gusset (57)

Corner bolted gusset (57) connects 1 to 10 braces to the corner where two parts meet, using a gusset plate. Welds the gusset plate to the first selected part that forms the corner. Creates optional clip angles, either at the ends of the braces, or on each side. Seals RHS or tube braces.

Situation	Description
	Brace profile: RHS Framing type: Column and extended end plate Gusset plate is welded to an extended end plate. Braces are pinned to the gusset plate.
	Brace profile: T, L Framing type: Column and extended end plate Gusset plate is welded to an extended end plate. Braces are bolted to the gusset plate.

Before you start

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

Selection order

Select the main part (the first part that forms the corner).

The gusset plate is connected to this part.
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.
Click the middle mouse button to create the connection.
