How does ideCAD control reinforced concrete shear wall design limits according to ACI 318-19?
The minimum wall thickness control is done automatically.
The wall dimensions are determined by the user.
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.
According to ACI 126.96.36.199, minimum wall thicknesses should be in accordance with ACI Table 188.8.131.52.
Minimum wall thicjness, h
1/25 the lesser of unsupported length and unsupported height
1/30 the lesser of unsupported length and unsupported height
Exterior basement and foundation
Earthquake Resistant Structures
Special structural walls
Concrete Shear Wall Design per ACI 318-19 §11, §18.10 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 dimensions such as (hw/lw) and (lw/bw).
