CVEN 4545 - Steel Design George.Hearn@colorado.edu BEAM SHEAR STRENGTH Shear strengths are computed for a set of steel W shapes. These are the same W shapes used in the example for beam section properties. AISC Specification Chapter G - Shear Strength The nominal shear strength of a W shape beam is the web area, multiplied by the shear yield strength and multiplied by a shear buckling factor, Cv . The approximate value of shear yield strength is y F shear y F 6 . 0 , The following shear strengths are obtained.

First we collect groups of W shapes at the same nominal depth. For all groups, the heavier sections have greater shear strength. That is, more steel means more strength.
