The maximum value of the (f_c^')^0.5 [or ] used to calculate V_c, V_s or ACI Eq. (22.5.1.2) is 100 psi. For calculation of V_c, V_s or ACI Eq. (22.5.1.2), it is assumed that the unit of (f_c^')^0.5 [or ] is psi. If these values are to be calculated in SI-metric or mks-metric units, the (f_c^')^0.5 [or ] value is changed accordingly. Strength reduction factor ϕ for shear, is determined as described in the Strength Reduction Factors title.
