To determine if longitudinal stiffeners are required on the web to give the main beams sufficient shear strength the procedure is as for intermediate stiffeners i e. Steel section web crippling web stiffener. 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. 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 design requirements for these stiffeners is found in scm j10 8. Transverse stiffeners for concentrated loads. X the diameter of circular openings is generally restricted to 0 5d. Figure 8 6 3 1 shows transverse stiffeners aka web stiffeners in a bridge application.
