1567 Concrete Contribution to Shear

For normal-density concrete, ACI 318-02 gives the following expression for the nominal shear carried by the concrete Vc:

where bw is the web width, d is the effective depth, and fc7 is the concrete compressive strength. ACI 318-02 limits the value of ^/f7 to 100 psi (25/3 MPa), unless the required amount of minimum shear reinforcement is provided.
