The American Concrete Institute (ACI) announced that a new edition of its “ACI 318-19 Building Code Requirements for Structural Concrete” publication is now available in print and digital formats.

In addition to online resources, the ACI is also hosting public and in-house seminars to introduce users to the changes. More information is available at the group’s website, concrete.org.

Major Technical Changes

Now with full-color illustrations to improve clarity, ACI 318-19 includes major technical changes in higher reinforcing steel yield strengths; the addition of shotcrete and deep foundation provisions; seismic requirements for deep foundations and other applications; vertical seismic motions; nonlinear analysis for seismic design; modification to development length equations; and updated shear design provisions and equations.

A variety of other industry needs are now addressed in ACI 318-19, including updates to provisions on post-tensioning, precast concrete, concrete durability, lightweight concrete, and more.

National Building Codes

ACI 318-19 identifies qualification training programs for inspectors/installers and lists certification requirements. According to the group, it is anticipated that the final code requirements of ACI 318-19 will be referenced in the 2021 International Building Code.

“The American Concrete Institute is pleased that the new ACI 318-19 is now available for our industry to use,” said Jack P. Moehle, chair of ACI Committee 318: Structural Concrete Building Code. “ACI 318 is one of the most essential and valuable standards with respect to the design of concrete structures. The United States and countries around the world base their national building codes on all or part of ACI 318.”

ACI 318-19 is available in print and digital formats at the website. Versions are currently available in English with inch-pound units and Spanish with SI units, with additional versions and languages coming soon.
