: Updated walkthroughs for the revised shear strength equations, which now account for the size effect in members without minimum shear reinforcement. Shotcrete Integration
The PCA Notes explain the new, more complex "size effect" factor for one-way shear in nonprestressed members without minimum shear reinforcement.
The transition to ACI 318-19 introduced several critical revisions to structural engineering workflows. The PCA Notes analyze these updates deeply, focusing on the underlying mechanics and giving concrete examples of how calculations shift under the new framework. 1. Deep Beam Provisions and One-Way Shear
The notes demonstrate how to leverage Grade 80 and Grade 100 reinforcement safely, leading to reduced steel congestion, easier concrete placement, and lower labor costs. pca notes on aci 31819
The PCA Notes provide step-by-step guidance on applying the new equation:
The 2019 edition of the code introduced some of the most significant changes in decades, all of which are meticulously detailed in the PCA Notes:
If you want to dive deeper into a specific design example, let me know if you would like me to outline the or the strut-and-tie method workflow based on the PCA manual. Share public link : Updated walkthroughs for the revised shear strength
Adjustments to the tension-controlled strain limit (
: Inspection requirements are now unified here, providing a clearer framework for engineers and inspectors. Structure and Navigation PCA Notes on ACI 318-11 Building Code - ISG Product
Determining if crack width is acceptable without calculation is no longer permitted in many jurisdictions. The PCA Notes present the new "Crack Control" provisions (using maximum bar spacing per Table 24.3.2) alongside the older z-factor method, highlighting which applies to your environment (interior vs. exterior exposure). The PCA Notes analyze these updates deeply, focusing

). The PCA Notes provides step-by-step guidance on navigating these complex, unified shear equations to avoid under-designing large beams or foundations. Deep Foundations and Strut-and-Tie Models (STM)
Published by the Portland Cement Association (PCA), this companion guide doesn’t just restate code provisions—it walks you through the why and how with detailed design examples, commentary, and step-by-step calculations.
