The American Concrete Institute expects to publish “ACI 318-19: Building Code Requirements for Structural Concrete,” in 2019.  The new edition is the first since the reorganized format was published in 2014 and includes new and updated code provisions along with updated color illustrations for added clarity. 

Chapter 17 on anchorage and ACI 318.2 on thin shells will be reorganized to follow the organizational philosophy of ACI 318-14. ACI expects new code provisions to be added on topics including 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 shearheads and composite concrete columns are expected to be removed.  

 It is anticipated that the final code requirements will be published and made available in June 2019, and be 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.  ACI 318-19 will be included in the ACI Collection of Concrete Codes, Specifications, and Practices, and educational seminars will begin in fall 2019.
