    I think...dt = depth of beam x thickness of the beam.

    Agreed. The reference equations should employ standard nomenclature for clarity.

    According to Equation G2-1 of the ANSI/AISC 360-16;

    Vn = 0.6FyAwCv1, Cv1 is 1.0 for rolled W-shaped

    This mean that the equation should indicate the “t” as tw = Web thickness. And d is the depth of the beam.

    (Shear Stress) v = V (Shear Force) / dtw

    This applies to flexure shear only. Torsional shear is looked at differently.
