The American Concrete Institute (ACI) is excited to announce the release of the 2025 edition of its flagship document, ACI CODE-318-25: Building Code for Structural Concrete – Code Requirements and Commentary. This updated edition is now available to ACI 318 PLUS platform subscribers and will be offered for purchase in print and digital formats through the ACI Store in early Spring 2025. ACI CODE-318-25 remains the definitive resource for the materials, design, and detailing requirements of structural concrete buildings and nonbuilding structures. Developed through an extensive consensus process, the document addresses all major structural systems, including cast-in-place, precast, shotcrete, plain, nonprestressed, prestressed, and composite construction. This latest edition introduces significant updates, including a new sustainability appendix that reflects modern construction practices, revised requirements for post-installed reinforcing bars, and enhanced provisions for shear friction. Additional updates include improvements to deep foundation requirements across all seismic design categories and clarified guidelines for cantilever and basement wall shear design. The document also features numerous advancements in seismic design provisions, the addition of a performance-based wind design appendix, and modifications to development length equations. Enhanced language on the development, embedment, and anchorage of reinforcement, as well as new strength reduction factors for breakout failure, are also included, along with updated guidance for developing closely spaced bars in tension. The comprehensive and user-friendly format of ACI CODE-318-25 ensures it remains indispensable for professionals in the concrete industry. Designed for adoption by reference in general building codes, the document allows seamless integration without altering its language. The accompanying Commentary continues to provide detailed explanations and recommendations to facilitate the application of the Code’s provisions. ACI CODE-318-25 will be available in multiple languages and units of measure to accommodate a global audience. Current ACI 318 PLUS subscribers will automatically receive access to the document upon its release, further enhancing their subscription benefits. ACI 318 PLUS is an interactive digital subscription platform that offers users convenient digital interactive access to ACI CODE-318-25 and ACI CODE-318-19 along with in-document access to related resources, robust digital notetaking, and enhanced search. ACI 318 PLUS also includes full digital interactive access to the ACI Detailing Manual and the ACI Reinforced Concrete Design Handbook. This includes functionality allowing subscribers to make digital notes alongside ACI CODE-318 provisions and commentary. ACI 318 PLUS is continually updated as new resources and references become available, ensuring you always have access to the latest tools and advancements in structural concrete design.
