Hollow brace wraparound gusset (59)

Hollow brace wraparound gusset (59) connects 1 to 10 braces to the corner where 2 or 3 parts meet, using a gusset plate. The gusset plate can be wrapped around the third part, usually a column. Bolts or welds the brace web to the gusset plate using connection plates, and bolts or welds the brace flange to the gusset plate using clip angles. Either connects the gusset plate directly to the existing parts, or uses clip angles or connection plates. Seals braces.
