Load & Resistance Factor Design for Shear in Buildings:
Based on the American Institute of Steel Construction (AISC)specifications for load-and-resistance factor design (LRFD)for buildings, the shear capacity Vu, kip (kN 4.448 xkip), of flexural members may be computed from the following:
Stiffeners are required when the shear exceeds Vu. In unstiffened girders, h/tw may not exceed 260.
In girders with stiffeners, maximum h/tw permitted is:
Maximum h/tw permitted is:
Fyf is the specified minimum yield stress, ksi, of the flange. For shear capacity with tension-field action, see the AISC specification for LRFD.
