Design for in plane shear (walls: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)
