Steel beam web stiffener analysis for concentrated loads steel beam web stiffener analysis for concentrated loads table version bs bf 2 tw 2 rounded down to nearest 1 2 inch stiffener width used. The equations for shear capacity are in part a function of k v which is a factor that accounts for the presence of transverse stiffeners.

Transverse stiffeners for concentrated loads. Scm g2 1 is used to compute the shear strength of steel beam webs. The clear spacing between such opening. Calculators for structural engineers construction professionals and steel building specifiers.

Both bearing and the compressive resistance of the system are check. Effective section of the stiffener acting with a portion of the web plate on each side of the stiffener. The axial force in the stiffener will be at a maximum immediately above the bearing and is dissipated over the length of the stiffener as load is shed into the web.
