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)
