AISC 360-22 Connection Design Checklist (Excel)

The AISC 360-22 Connection Design Checklist (Excel) is a structured, spreadsheet-based engineering resource that guides structural engineers through the systematic verification of steel connections in accordance with the 2022 AISC Specification for Structural Steel Buildings. It organizes design steps, code references, calculation prompts, and compliance checks into tabular format to reduce omissions and enhance traceability. The checklist supports both bolted and welded connections for common configurations—including shear tabs, moment end-plates, double-angle, and T-stub connections—while enforcing limit states per Chapter J and referenced provisions.

📖 Overview

This Excel-based checklist operationalizes the prescriptive and performance-based requirements of AISC 360-22 Chapter J (Design of Connections) and related sections such as Chapter D (Design Requirements), Chapter B (Design Requirements for Stability), and Appendix 1 (Load and Resistance Factor Design). It embeds logical validation rules (e.g., conditional formatting for overstress, dropdown menus for connection type and loading condition) and integrates key design workflows: load path verification, fastener layout assessment, weld sizing per AISC Part 8, bearing and tear-out checks, block shear evaluation per Section J4.3, and prying action analysis where applicable. Each worksheet typically corresponds to a connection category and includes embedded hyperlinks to relevant AISC 360-22 clauses, AISC Design Guides (e.g., DG29 for bolted connections), and illustrative sketches or reference tables (e.g., minimum edge distances, bolt group coefficients). The tool promotes consistency across project teams, facilitates peer review by documenting assumptions and code citations, and serves as an auditable record for quality assurance—especially valuable in regulated infrastructure and high-rise projects where connection reliability directly impacts life safety and serviceability.

📑 Key Components

1 Connection Type Selector (dropdown)
2 Load Input & Factored Force Summary
3 Code Compliance Verification Matrix (with pass/fail flags)

🎯 Applications

  • Pre-submittal internal design review for structural steel packages
  • Training aid for early-career engineers learning AISC 360-22 connection logic
  • QA/QC documentation for third-party plan reviewers and building officials

📐 Key Formulas

Block Shear Strength (LRFD)

φRn = φ[0.6FyAgv + UbsFuAnv] ≤ φ[0.6FuAnv + UbsFuAnt]

Calculates nominal block shear strength for coped beams and gusset plates per AISC 360-22 Section J4.3, using resistance factor φ = 0.75

Bolt Shear Strength (LRFD)

φRn = φFnAb

Determines available shear strength per bolt, where φ = 0.75, Fn is nominal shear stress (e.g., 48 ksi for A325-X), and Ab is bolt area

Weld Strength (LRFD)

φRn = φ(0.60FEXX)(w)(L)

Computes available strength of a fillet weld per AISC 360-22 Section J2.4, where φ = 0.75, FEXX is electrode strength, w is effective throat, and L is weld length
