: Detailed guidance on the new provisions allowing for reinforcement yield strengths up to 100,000 psi (Grade 100) for most applications, including seismic design. Deep Beam and Shear Design
: Member design (Beams, One-way slabs, Two-way slabs, Columns, Walls, Diaphragms).
: 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 pca notes on aci 31819
The PCA notes highlight that stronger rebar may lack the benchmark properties of lower-strength steels, such as required strain-hardening and elongation.
The updated code provides expanded guidance on detailing, reinforcing, and material specifications, including selecting durable aggregates. A design guide helps engineers follow this advice, preventing common pitfalls like the inappropriate use of lightweight aggregates in structural applications. : Detailed guidance on the new provisions allowing
) in one-way shear and updated punching shear equations for two-way slabs.
Stricter requirements for confinement in columns. Crossties: Changes in how hooks must be oriented. Structure and Navigation PCA Notes on ACI 318-11
The practical guidance is crucial for both new and experienced engineers, helping to avoid errors, save design time by providing ready-to-use calculations, and ensuring projects are safe, code-compliant, and cost-effective. For example, knowing when to apply the new shear equations can prevent overly conservative designs, while proper seismic detailing ensures life-safety performance.
