Flat plate design is notorious for punching shear failures. The 2019 code changed the critical section location for stud rails. The PCA Notes include – a full-page, worked example of a slab-column connection with moment transfer, showing exactly how to apply the $\gamma_v$ and $\gamma_f$ factors using the revised perimeter $b_o$.

ACI 318-19 significantly expanded the permitted use of high-strength rebar. The code now allows for yield strengths ( pca notes aci 318-19

The "PCA Notes" is a publication by the Portland Cement Association (PCA). Its full title is typically Notes on ACI 318-19 Building Code Requirements for Structural Concrete with Design Applications . Flat plate design is notorious for punching shear failures

The PCA Notes ACI 318-19 is available in both hardcover (spiral-bound preferred for desk use) and PDF. ACI 318-19 significantly expanded the permitted use of

Where ACI 318-19 is terse or open to interpretation (e.g., minimum skin reinforcement for deep beams, definition of “transfer” vs. “non-transfer” columns in seismic design), the PCA Notes offer engineering judgement and industry consensus.

The PCA Notes on ACI 318-19 is the definitive companion to the ACI 318-19 Code. While the Code itself provides requirements , the PCA Notes provide the application . This edition successfully bridges the significant reorganization of ACI 318-19 (moving to a "reference to reference" format) with over 400 worked examples. For any engineer designing concrete structures in the U.S., this is not an optional supplement—it is a daily necessity.

The PCA Notes mirror this new structure, reorganizing examples into eight primary parts, but the most critical changes for the designer are:
