For disturbed regions (D-regions) like deep beams, corbels, pile caps, and beam-column joints.
: New sections on the design of drilled piers and piles, which were moved into the main body of ACI 318-19. Structural Organization
Instead of calculating the area of 3 #6 bars manually, use Table 3 (Area of Reinforcement). pca notes on aci 31819
: Explicit inclusion of shotcrete as a placement method within the code's scope for the first time.
A continuous T-beam needs to be designed for a 30-ft span, f'c = 5,000 psi , fy = 60,000 psi , with a superimposed dead load of 1.5 kip/ft and live load of 2 kip/ft. The beam is in an interior, dry environment. For disturbed regions (D-regions) like deep beams, corbels,
If you are using the (DDM) for flat plates/slabs:
The PCA Notes on ACI 318-19 remains an indispensable resource for structural engineers transitioning to the latest code. By walking through realistic design examples, it clarifies ambiguous provisions, reduces calculation errors, and promotes safe, economical concrete design. This paper summarized the core topics covered, from flexure and shear to seismic design and strut-and-tie modeling. For detailed step-by-step calculations, the original PCA Notes document is highly recommended as a daily reference. : Explicit inclusion of shotcrete as a placement
The shear design provisions underwent significant scrutiny and refinement in the 2019 edition.
