ACI is accepting feedback through February 6 on the proposed ACI 318-19: Building Code Requirements for Structural Concrete, the draft posted here. The new edition will be the first since a reorganized format was published in 2014 and include new or updated provisions on transverse reinforcement and shear in wide beams, hanger reinforcement, bi-directional interaction of one-way shear, and reference to ACI certifications. Existing provisions expected to receive significant updates and clarifications include two-way shear strength, ordinary walls, seismic loads, reinforcement detailing, analysis, and numerous materials requirements. Analysis methods for two-way slabs and provisions on shear heads and composite concrete columns are expected to be removed.
ACI anticipates final code requirements will be published by June 2019 and referenced in the 2021 International Building Code. Printed and digital formats of ACI 318-19 are expected, as well as versions in inch-pound units, SI units, and other languages. The document will be included in the ACI Collection of Concrete Codes, Specifications, and Practices, and the focus of educational seminars beginning in fall 2019.
