castellated-cellular-design

AISC DG31 castellated and cellular beam design involves selecting opening geometry, checking web post buckling and Vierendeel bending, and validating composite or noncomposite capacity. This Skill provides step-by-step workflows, formulas, and worked examples across all three chapters to convert code provisions into actionable calculations.

Web post buckling occurs when the thin vertical webs between openings fail in compression; Vierendeel bending develops moment in those webs when the beam acts as a moment frame. DG31 provides check procedures for both failure modes, which this Skill applies with geometry calculators and on-demand verification tools.

Yes. Castellated and cellular beams suit parking structures, residential, and commercial buildings under different loading and composite conditions. This Skill includes DG31 workflows and worked examples tailored to each application context, with guidance on composite versus noncomposite design decisions.

DG31 opening geometry nomenclature—such as distance between openings, opening height, and cell configuration—directly affects web post and Vierendeel checks. This Skill provides geometry calculators, symbol references, and chapter procedures to define and validate opening layout before running capacity calculations.

Composite beams develop shear connection with a concrete deck; noncomposite beams do not. DG31 Chapter 3 procedures and worked examples in this Skill show how to apply each check separately and compare results, helping you determine which approach fits your project constraints.

Chapter 4 of DG31 contains solved examples; Chapters 1–3 contain formulas and procedures. This Skill indexes both, offering quick access via example matching, formula queries, and calculation queries so you can jump directly to the guidance matching your problem.
