For the first time, shotcrete (sprayed concrete) is explicitly integrated into the main body of ACI 318. It is no longer treated as a specialty material governed by separate standards.

) up to 100,000 psi (Grade 100) for specific applications. The PCA Notes provide essential commentary on the implications of Grade 100 steel, specifically addressing:

: Updated walkthroughs for the revised shear strength equations, which now account for the size effect in members without minimum shear reinforcement. Shotcrete Integration pca notes on aci 31819

The primary successor to the PCA Notes is the CRSI Design Guide. Engineers can purchase it directly from the , choosing from print, digital, or bundle options. The official ACI 318-19 code and commentary are sold separately by organizations like the American Concrete Institute, Techstreet, and other standards retailers. The bundle of the CRSI Design Guide and the official ACI 318-19 code provides a comprehensive design toolkit.

The design guides aligned with PCA methodologies, like the Design Guide on the ACI 318 Building Code Requirements for Structural Concrete , are designed to simplify the transition to the 2019 code. 1. Material and Strength Requirements

: For the first time, shotcrete is fully integrated into the code. The PCA notes clarify the design and inspection requirements now unified with traditional cast-in-place concrete. Development Lengths

The new equations explicitly incorporate the longitudinal reinforcement ratio ( ρwrho sub w

The PCA Notes explain the new, more complex "size effect" factor for one-way shear in nonprestressed members without minimum shear reinforcement. Can’t copy the link right now

📘 Don’t just read the PCA Notes passively. Keep a copy next to ACI 318-19 and work through each design example manually. The commentary reveals common pitfalls and code interpretations that exam prep (like the SE or PE) often tests.

With the increasing use of shotcrete in structural walls, ACI 318-19 integrated explicit requirements for its materials, placement, and inspection, particularly for seismic applications. The PCA Notes provides clarity on how to apply these rules to high-seismic zones (Seismic Design Categories D, E, and F). 3. Structural Organization of the Manual

Clarifying the new, more restrictive geometry rules for standard hooks to prevent concrete breakout failure before the high-strength steel reaches its full yield potential. Step-by-Step Design Examples: The Real Value
