The code's equations for development length (ld) are straightforward but involve multiple modification factors (casting position, coating, lightweight concrete, etc.). The PCA Notes offer a single, unified worksheet to plug in variables and get ld directly. Additionally, a full table of standard hook development lengths for Grade 60 rebar is provided.
One of the most valuable aspects of the PCA Notes is the "Design Procedure" sections found at the start of most chapters.
Example: Designing a Rectangular Beam (Chapter 9) Instead of hunting through ACI 318-19 Sections 9.3.3, 9.7, etc., the PCA Notes provides a numbered list: pca notes on aci 31819
Why this matters: This workflow ensures you don't miss a code requirement (like minimum cover or crack width) that might be buried in a different section of the code.
The ACI 318-19 code is mandatory reading. But mandatory reading is often dry, obtuse, and unforgiving to the uninitiated. The PCA Notes on ACI 318-19 is the translation layer that turns legal clauses into confident design decisions. The code's equations for development length ( ld
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:
If you own ACI 318-19, the PCA Notes is not an optional supplement – it’s the other half of the book. Order the 2019 edition (ISBN: 978-0-89312-309-9) directly from the Portland Cement Association or through major technical bookstores. Keep it within arm’s reach of your code. Your future self, during a 2 AM deadline, will thank you. Why this matters: This workflow ensures you don't
This is the most used section for concrete design.
