Transverse Reinforcement Detailing (BRD)
Transverse reinforcement detailing is applied automatically in accordance with Codes.
Transverse reinforcement detailing is applied according to Codes in earthquake resistant structure beams.
International Design Codes
ACI 318-19 : Transverse Reinforcement (BRD) per ACI 318-19 with ideCAD
TSC 2018 : Transverse Reinforcement Detailing for Beams.
Notation in ACI 318-19
Ag = gross area of concrete section, in2
bw = web width or diameter of circular section, in.
bt = width of that part of cross section containing the closed stirrups resisting torsion, 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' = specified compressive strength of concrete, psi
√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.
ph = perimeter of centerline of outermost closed transverse torsional reinforcement, in.
s = center-to-center spacing of items, such as longitudinal reinforcement, transverse reinforcement, tendons, or anchors, in.
Ve = design shear force for load combinations including earthquake effects, lb
Vn = nominal shear strength, lb
Vs = nominal shear strength provided by shear reinforcement, lb
Vu = factored shear force at section, lb
ϕ = strength reduction factor
Details of transverse reinforcement are applied in accordance with Codes.
