Shear Capacity (ASCE)
The Shear capacity is calculated according to ASCE as indicated below:
Columns
The Shear capacity of columns is calculated through the following expression according to section 4.2.3.1 of ACI 369.1-22.
Shear Walls
The shear strength of a shear wall is calculated from the following expression:
Note: The value for Vn at any horizontal section for shear in plane of wall shall not be taken greater than 
according to section 11.5.4.3 of ACI 318-19.
Beams
The shear capacity of beam sections is calculated from the equation (22.5.1.1) of ACI 318-19, with the shear strength provided by the transverse reinforcement computed from equation (22.5.8.5.3) of ACI 318-19 and the shear strength provided by concrete computed by the detailed calculation of section 22.5.5.1 of ACI 318-19.
FRP Wrapping
The shear resistance Vn, may be calculated from expression (4.2.3.1) of ACI 369.1-22 for columns or the equation (22.5.1.1) of ACI 318-19 for beams and shear walls adding in Vs the contribution of the FRP jacket to the shear resistance.
The contribution of the FRP jacket to the shear resistance is computed through the following expression multiplied by a reduction factor ψf, as described in section 11.4 of ACI 440:
where
and
Note: The total shear strength provided by the sum of the FRP shear reinforcement and the steel shear reinforcement should be limited as indicated in the equation below:
