Transverse reinforcement is divided into 3 zones which vary from PCI BDM to AASHTO LRFD. PCI BDM defines these zones as Ordinary, Intermediate, and Special. AASHTO LRFD defines these zones as “Seismic Zone 1”, “Seismic Zone 2”, and “Seismic Zones 3 and 4”.

ACI
ACI defines their zones to be aligned with the 2018 IBC. ACI uses Seismic Design Categories (SDC) and 318-19 breaks them into 3 distinct sections. Section one is SDC A&B, section two is SDC C, and section three is SDC D,E, & F.
PCI
PCI defines their zones to be more aligned with ACI 318-19 and the 2018 IBC. The equations are based on ductility considerations which, according to the PCI BDM, are more appropriate for use with prestress piles in seismic regions.
