Longitudinal Reinforcement Detailing (SwRD)
Longitudinal reinforcement detailing is applied automatically in accordance with Codes.
Longitudinal reinforcement detailing is applied according to Codes in special structural walls.
International Design Codes
ACI 318-19 : Longitudinal Reinforcement (SwRD) per ACI 318-19 with ideCAD
TSC 2018 : Shearwall Web Reinforcement Detailing
Notation in ACI 318-19
Ag = gross area of concrete section, in2
Ast = total area of nonprestressed longitudinal reinforcement, in2
bw = web width or diameter of circular section, in.
d = distance from extreme compression fiber to centroid of longitudinal tension reinforcement, in.
db = nominal diameter of bar, wire, or prestressing strand, in
√fc‘ = square root of specified compressive strength of concrete, psi
fy = specified yield strength of nonprestressed reinforcement, psi
fyt = specified yield strength of transverse reinforcement, psi
h = overall thickness, height, or depth of member, in.
hsx = story height for story x, in.
hw = height of entire wall from base to top, or clear height of wall segment or wall pier considered, in.
ld = development length in tension of deformed bar, deformed wire, plain and deformed welded wire reinforcement, or pretensioned strand, in.
lw = length of entire wall, or length of wall segment or wall pier considered in direction of shear force, in.
Mu = factored moment at section, in.-lb
s = center-to-center spacing of items, such as longitudinal reinforcement, transverse reinforcement, tendons, or anchors, in.
Vu = factored shear force at section, lb
ϕ = strength reduction factor
