Braced cantilevered beam above the bottom flange
Braced cantilevered beam above the bottom flange
(OP)
I was recently performing a structural survey of an existing building in order to find the capacity of the roof. In one of the middle spans, a W24 beam cantilevered both ways over the columns to support the beams in the adjacent bays. At the beam column connection, an 18" deep bar joist had a bottom chord extension that was intended to brace the bottom flange of the beam. However, the bottom chord extends straight and braces the beam 6" above the bottom chord. Is the cantilevered beam considered braced at the column?

I don't think that Modern Steel Construction is suggesting that compression flange bracing may be omitted because the tension flange is braced. That would be wrong.
