• Transverse reinforcement detailing is applied automatically in accordance with Codes.

  • Transverse reinforcement detailing is applied according to Codes in special structural walls.


International Design Codes

ACI 318-19 : Transverse Reinforcement (SwRD)

TSC 2018 : Shearwall Web Reinforcement Detailing


Notation in ACI 318-19

Acv = gross area of concrete section bounded by web thickness and length of section in the direction of shear force considered in the case of walls, and gross area of concrete section in the case of diaphrams. Gross area is total area of defined section minus area of any openings, in.2
Acw = area of concrete section of an individual pier, horizontal wall segment, or coupling beam resisting shear, in2.
fc' = specified compressive strength of concrete, psi
√fc = square root of specified compressive strength of concrete, psi
fy = specified yield strength of nonprestressed reinforcement, psi
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.
s = center-to-center spacing of items, such as longitudinal reinforcement, transverse reinforcement, tendons, or anchors, in.
Vn = nominal shear strength, lb
Vu = factored shear force at section, lb
ϕ = strength reduction factor
