Perimeter beam design
Perimeter beam design
(OP)
I am reviewing the structural steel design for a school. The building is 2 storeys with steel beam/column framing and open web steel joists. The walls consist of vertical steel studs between columns. The studs are connected at the bottom to the concrete floor slab and connected to the top at the underside of steel I beam.
For wind analysis, the studs will distribute a portion of the wall load to the connection at the I beam. Since the joists are connected to the top flange, what is the best approach to check for the additional load in the beam between supports?
Also, the columns only see a small tributary portion of wind load. Correct?

Lateral wind forces from studs to the beam flange are usually resisted by the flange spanning between supports. Diagonal braces from flange to joist or bottom chord extensions of the joists are sometimes used to reduce the span so that the combined stresses in the flange are acceptable.

You will have the benefit of likely having a good portion of the dead load in place by the time the metal studs are installed.
