ACI 318-19 errata 2022 PDF

Full title and description

St ACI 318-19 errata 2022 — compiled corrections and editorial/technical clarifications to ACI 318-19: Building Code Requirements for Structural Concrete and Commentary (the 2019 code), consisting of the formal errata issued against the 2019 Code during 2022. The errata document updates wording, table references, equations, and figure/text corrections to ensure the published Code and Commentary reflect committee intent and tested provisions.

Abstract

This product page summarizes the 2022 errata for ACI 318-19. The 2022 errata set includes multiple dated corrections (examples: March 2, 2022; July 7, 2022; September 29, 2022 and other 2022 updates) addressing editorial errors, incorrect cross-references, punctuation that changes interpretation, table and equation fixes, and a small number of technical clarifications (for example, provisions related to punching shear, tendon placement/integrity, and certain detailing/calculation clarifications). These errata are intended to be used together with the 2019 Code/Commentary (reapproved 2022).

General information

• Status: Active — ACI 318-19 (Code and Commentary) with errata included; reapproved in 2022.
• Publication date: Code year 2019 (ACI 318-19); errata issued in multiple 2022 releases (examples: January 31, March 2, July 7 and September 29, 2022 as published by ACI/committee records).
• Publisher: American Concrete Institute (ACI).
• ICS / categories: Structural design / building codes; ICS around Structures of buildings (commonly listed under 91.080 series for building structures).
• Edition / version: ACI CODE‑318‑19 (2019 edition) — Code and Commentary; reapproved 2022 with errata updates issued during 2022.
• Number of pages: Approximately 620–630 pages for the combined Code and Commentary (published 2019 printing typically cited as ~624 pages depending on format/print).

Scope

The errata set corrects and clarifies discrete provisions, figures, tables, and commentary within ACI 318-19 without changing the underlying scope or intent of the Code. Users should apply the errata in conjunction with the full 2019 Code and Commentary when designing and detailing structural concrete members (cast‑in‑place, precast, prestressed/non‑prestressed, shotcrete, composite systems) and when referencing ACI 318 provisions in contract documents. The errata are primarily editorial and corrective, but some fixes remove ambiguity that could affect design/calculation interpretation.

Key topics and requirements

• Corrections to punching‑shear related wording and table cross‑references (e.g., revisions to R8.6.1.2 and related two‑way shear table references to ensure correct application of slab shear provisions).
• Clarifications on tendon placement and structural integrity tendon sequencing/positioning in prestressed two‑way slabs and caps (e.g., revisions in R8.7.5.6.x to remove wording ambiguities).
• Punctuation/cross‑reference fixes that affect interpretation of reinforcement development/anchorage provisions (example: removal of an incorrect comma in R9.7.3.8.3 clarifying the limiting length variable ℓd).
• Table and appendix corrections (e.g., Table 9.6.3.1 and Appendix C equivalence/size‑effect equation clarifications added or corrected in the errata sequence).
• Editorial corrections to figures, captions, and commentary paragraphs to align published text with committee intent and with referenced test data or formulas.

Typical use and users

Engineers (structural and civil), code officials, architects, specifiers, educators, and construction quality personnel use the 2022 errata to ensure that designs, plans, specifications, and reviews referencing ACI 318-19 apply the corrected wording and computations. The errata are a maintenance document to be applied by users of the 2019 Code/Commentary.

Related standards

Related ACI codes and guides commonly used with ACI 318 include the ACI Detailing Manual, ACI Reinforced Concrete Design Handbook (MNL‑17), and related ACI product codes (for example ACI CODE‑440 series for FRP reinforcement). Jurisdictional building codes and referenced ASTM standards remain companion references for materials, testing, and specific detailing practices.

FAQ

Q: What is this standard?

A: This is the errata collection for ACI 318-19 (Building Code Requirements for Structural Concrete and Commentary, 2019 edition) listing the formal corrections and clarifications issued by ACI Committee 318 during 2022; it is used together with the full 2019 Code and Commentary.

Q: What does it cover?

A: It covers editorial corrections, corrected cross‑references and tables, minor technical clarifications (where wording affected interpretation), and figure/table fixes across the Code and Commentary. The errata do not reformat or replace the Code—users must apply errata to their copy of ACI 318-19.

Q: Who typically uses it?

A: Structural engineers, designers, code officials, specifiers, reviewers, and educators who rely on ACI 318-19 for design and inspection use the errata to ensure correct application of the provisions.

Q: Is it current or superseded?

A: The errata amend the 2019 edition (ACI 318-19). The 2019 Code was reapproved in 2022 and the errata were issued during 2022 to correct that edition. Users should confirm whether a newer edition or reissue of ACI 318 has been published after 2019/2022 for their jurisdiction; the errata do not themselves constitute a new edition.

Q: Is it part of a series?

A: Yes — ACI CODE‑318 is part of ACI’s family of codes and commentaries (Code + Commentary + related manuals and design handbooks); the errata specifically apply to the ACI 318-19 Code/Commentary pair.

Q: What are the key keywords?

A: ACI 318-19, errata, structural concrete, punching shear, tendon integrity, code corrections, commentary, design code.
