). This factor accounts for the reality that deeper concrete members exhibit lower unit shear strength than shallower ones.

The PCA Notes on ACI 318-19 provide comprehensive guidance for structural engineers, translating updated code requirements into practical applications through in-depth explanations and design examples. Key updates covered include high-strength reinforcement, revised shear provisions, and expanded strut-and-tie method requirements for the 2019 code. You can find the publication at the Portland Cement Association (PCA). PCA Notes on ACI 318-19 (published by the

): This accounts for the fact that deeper members may have a lower unit shear strength. Reinforcement Ratio ( ρwrho sub w This link or copies made by others cannot be deleted

ACI 318-19 fundamentally changed how engineers calculate one-way shear strength. For members without minimum shear reinforcement, the new code introduces a size effect factor ( λslambda sub s

Because the code itself is written in legal language meant for adoption into local building regulations, it can be dense and difficult to interpret in daily engineering practice. The PCA Notes bridge this gap by translating complex code provisions into clear, practical design procedures, complete with explanations of the background logic and worked-out design examples. Key Changes Covered in the PCA Notes

Updates to the formulas to account for the higher yields of these steels. 5. Development and Splicing of Reinforcement

Screw anchors are now officially included in Chapter 17 of ACI 318-19.
