A traditional "PCA Notes" volume specifically for ACI 318-19 was not formally released; instead, technical guidance has shifted to the CRSI Design Guide and official ACI resources. Key updates in ACI 318-19, often detailed in replacement literature, focus on shear design, deep foundation alignment, high-strength reinforcement, and precast diaphragms. Detailed information regarding the transition is available at
Perhaps the most significant update in ACI 318-19 is how shear strength ( Vccap V sub c pca notes on aci 31819
Discussion of Intent: It includes background discussions that explain the "why" behind specific code provisions. Key Technical Updates in the ACI 318-19 Edition A traditional "PCA Notes" volume specifically for ACI
Starting with ACI 318-14 (and continued in ACI 318-19), the code was split into three parts: Shear Friction ($V_n$): The upper limit for shear
Example excerpt:
Given ( f'_c = 4,000 , \textpsi ), ( f_y = 60,000 , \textpsi ), ( b = 12 , \textin ), ( d = 22.5 , \textin ), ( M_u = 300 , \textkip-ft ).
Compute ( R_n = M_u / (\phi b d^2) ), find ( \rho ), then ( A_s = \rho b d ).
Shotcrete: Guidance on the full integration of shotcrete into the code, which was previously handled by separate documents.
