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.
