Tube gusset (20)

Tube gusset (20) connects 1 to 10 hollow braces to a beam or a column using a gusset plate. The braces need to have a rectangular hollow section (RHS) or a tube profile. The connection bolts the braces to the gusset plate using a connection plate and an optional tongue plate. The hollow braces can be sealed with end plates.
