The minimum wall thickness control is done automatically.
Notation
bw = the width of the web of the wall segment, in.
h = overall thickness, height, or depth of member, in.
hw = height of entire wall from base to top, or clear height of wall segment or wall pier considered, in.
lw = length of entire wall, or length of wall segment or wall pier considered in direction of shear force, in.
Accorting to ACI 11.3.1.1, minimum wall thicknesses should be in accordance with ACI Table 11.3.1.1.
Earthquake Reistant Structures
Special structural walls
Concrete Shear Wall Design title also contains requirements for the dimensions and details of special structural walls and all components. Design provisions for special structural walls depend on the ratio of the wall dimentions such as (hw/lw) and (lw/bw).
