Concrete Diaphragm Shear Capacity

This calculation determines the shear capacity of a reinforced-concrete diaphragm according to ACI 318 or CSA A23.3

Input:

psi
ksi
in
in2
in
reinforced concrete diaphragm

Output:

  1. Definitions
    • ϕv = Resistance factor for shear
    • fc = Specified concrete strength (psi)
    • fy = Specified reinforcing steel yield strength (ksi)
    • ts = Slab / member thickness (in)
    • Ab = Area of 1 distributed rebar (in2)
    • s = Spacing of rebar (in)
  2. Concrete shear capacity
    • kip/ft
  3. Reinforcing steel shear capacity
    • kip/ft
  4. Maximum Limit for shear capacity
    • kip/ft
  5. Total shear capacity
    • kip/ft
