06 16 2011 if a beam has insufficient strength web local yielding or web crippling to support concentrated point loads then a pair of transverse stiffeners can be added to the web to transfer the concentrated force to the web. 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. This information must be read or used in conjunction with can csa s16 01 limit states design of steel structures and the cisc handbook of steel construction 9th ed. Effective section of the stiffener acting with a portion of the web plate on each side of the stiffener.

The clear spacing between such opening. 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. 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. X the diameter of circular openings is generally restricted to 0 5d.
