Pca Notes On Aci 31819

Seismic design provisions in Chapter 18 were heavily updated to match the latest findings from recent earthquakes and laboratory testing. Major changes target special moment frames, structural walls (shear walls), and precast concrete systems.

The PCA Notes is not the ACI Code. It is a companion . You cannot design with the Notes alone; you must have a copy of ACI 318-19 at your side. However, the Notes will teach you how to correctly interpret and apply that code.

However, this brings us to a critical point. The most recent editions of the "PCA Notes" were published for ACI 318-05, 318-08, and 318-11. Free PDF editions of the "Notes on ACI Building Codes" for ACI 318-11 are available on the PCA website. For later editions of the code (ACI 318-14 and ACI 318-19), PCA decided to pass the baton of providing these detailed, example-filled design guides to the Concrete Reinforcing Steel Institute (CRSI). Therefore, while the "PCA Notes" as a published title for ACI 318-19 does not currently exist, the need for their practical, example-driven content is now fulfilled by CRSI’s design guides.

If you are using the (DDM) for flat plates/slabs:

The notes feature complete calculations for two-way floor systems using both the Direct Design Method and the Equivalent Frame Method. The examples incorporate the ACI 318-19 calculation adjustments for slab-column joints, punching shear perimeter calculations, and the updated calculation for the modification factor used in unreinforced joints.

The Notes offer rigorous, fully worked examples for direct design and equivalent frame methods—including moment transfer at edge columns, a common pain point.

The 2019 edition of the PCA Notes is organized into 27 chapters, mirroring the code’s structure but with added commentary, flowcharts, and solved problems. Here are its core components:

The PCA Notes for the 19-cycle focus heavily on several major shifts in the code:
