Shear Wall Required and Design Strength.

  • Wall required strengths are calculated automatically.

  • Wall design strengths are calculated automatically.

TSC 2018 : Shearwall Design For Flexure and Axial Force Shear Design of Shearwalls

Notation in ACI 318-19

Ag = gross area of concrete section, in2
Av = area of shear reinforcement within spacing s, in.2
D = dead load
E = earthquake load
fc' = specified compressive strength of concrete, psi
fyt = specified yield strength of transverse reinforcement, psi
L = live load
Lr = roof live load
Mn = nominal flexural strength at section, in.-lb
Mu = factored moment at section, in.-lb
Pn = nominal axial compressive strength of member, lb
Pu = factored axial force; to be taken as positive for compression and negative for tension, lb
R = rain load
S = snow load
U = strength of a member or cross section required to resist factored loads or related internal moments and forces in such combinations
Vn = nominal shear strength, lb
Vu = factored shear force at section, lb
W = wind load
ϕ = strength reduction factor
