torsional bracing of columns

torsional bracing of columns

torsional bracing of columns

(OP)
I have a column that is failing due to the interaction equation. The unbraced length is conservative, which lowers my axial capacity and therefore the column fails. Although I have a girder framing into the column from the south but not the north. Beams frame into the girder at a distance of 1'-9" south of the beam end. (the end that frames into the column). Seeing that the column is only braced in one direction, the unbraced length for the other direction is much higher. I was wondering if I can consider the column braced in both directions seeing that the beams that frame into the girder are so close to the end of the girder, and you could consider the column braced in both directions. I think there's something in the steel manual about this but I cant find it.

RE: torsional bracing of columns

You can treat the 1'9" beam portion as a cantilever from the diaphragm and use AISC Appendix 6 to check its strength and stiffness for the required bracing force. I would imagine you could get this to work.
