• If a member bottom flange is braced for torsional buckling at it's midpoint and end, should I be specifying UNB for those points or is the end node already covered?

    I am modeling an existing warehouse and I'm working on inputting all the design parameters. I have a rafter beam that is braced at the midpoint and end for torsion. How would I specify bracing at these points?
