where Aoh is the area enclosed by the centerline of the outermost closed transverse torsional reinforcement (sq. in.) and ph is the perimeter of the centerline of the outermost closed transverse torsional reinforcement (in.).

The sum of the stresses at the left-hand side of Equation 8.71 should not exceed the stresses causing shear cracking plus 8yfr. This is similar to the limiting strength for Vs < 8yf for shear without torsion. The strength of the plain concrete in the web is taken as
