I wonder why full stabilization of a beam (for example by diaphragm bracing) is: S*=1/2*A/fy
In which S* is stiffnes of bracing (diaphragm), the Shear Force needed to create an angle of 1 rad, so the Shear Force needed to deform 1 inch over one inch length of diaphragm.
1/2 is a half
fy = yield stress of steel beam, let's say i-profile
A = area of i-profile
