Flexural Reinforcement Detailing (BRD)
Longitudinal reinforcement detailing is applied automatically in accordance with Codes.
Longitudinal reinforcement detailing is applied according to Codes in earthquake resistant structure beams.
International Design Codes
ACI 318-19 : Flexural Reinforcement (BRD)
TSC 2018 : Longitudinal Reinforcement Detailing for Beams.
