Slabs are notoriously difficult to visualize mathematically under the new rules. The PCA Notes include fully worked numerical examples for flat plate configurations, mapping out the precise step-by-step evaluation of the critical section for punching shear under unbalanced moments. 3. Short and Slender Columns (Chapters 10 & 22)
For the first time, shotcrete (sprayed concrete) is explicitly integrated into the main body of ACI 318. It is no longer treated as a specialty material governed by separate standards.
ACI 318-19 increased the minimum reinforcement required for beams and one-way slabs to control cracking. The PCA Notes provide corrected tables comparing the old 200/fy formula with the new, more rational 0.5√(f'c)/fy requirement, showing exactly when the new rule governs.
For disturbed regions (D-regions) like deep beams, corbels, pile caps, and beam-column joints. pca notes on aci 31819
Architectural-grade reinforcement details illustrating lap splices, clear spacing, and hook orientation.
Strut-and-Tie Modeling (STM) changed from an alternative option to the mandatory method for deep beams, corbels, and structural joints.
The is an essential companion manual produced by the Portland Cement Association (PCA) that explains the practical application of the ACI 318-19 building code. It is widely considered a "good feature" for structural engineers because it bridges the gap between raw code requirements and real-world design execution . Key Features of PCA Notes on ACI 318-19 Short and Slender Columns (Chapters 10 & 22)
The ACI 318-19 code introduced several substantial technical shifts that these notes clarify: High-Strength Reinforcement
The official title is
The primary successor to the PCA Notes is the CRSI Design Guide. Engineers can purchase it directly from the , choosing from print, digital, or bundle options. The official ACI 318-19 code and commentary are sold separately by organizations like the American Concrete Institute, Techstreet, and other standards retailers. The bundle of the CRSI Design Guide and the official ACI 318-19 code provides a comprehensive design toolkit. The PCA Notes provide corrected tables comparing the
: It provides fully worked design solutions to real-world structural problems, making it a staple for both practitioners and educators.
Many engineers confuse the PCA Notes with similar documents:
Whether you are prepping for the PE exam, updating your firm’s standard details to the 2019 code, or simply trying to understand why ACI calls for a particular factor of safety, the PCA Notes on ACI 318-19 is the single best investment you can make in your concrete design career.
Whether you are sizing a single footing for a sign structure or leading a 20-story core-wall building, the PCA Notes does three things no other document does:
