Wraparound gusset (58)

Wraparound gusset (58) connects 1 to 10 braces to the corner where two or three parts meet, usually two beams and a column, 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 two beams, or uses clip angles or shear tabs, or connection plates. The brace profile can be C or W.
