Design for in plane shear (concrete wall:ACI 318)

In the plane of the wall the factored shear must be equal to or less than the design shear strength of the wall

Vu ΦVn
    

The design shear strength of the wall is equal to the design shear strength of the concrete plus that of the shear reinforcing

Vu ΦVc + ΦVs
    

The shear strength, Vn, may not be taken greater than 10 * √f’c * h * d.

Vn 10 * √f’c * h * d US units
Vn 0.83 * √f’c * h * d metric units
    

where

h = wall thickness
d = 0.8 * lw
lw = length of the wall
    

Out of plane the shear design calculations are the same whether the design element is a column or a wall - see: Design parameters for shear (column and wall:ACI 318)
