AISC 360-22 Steel Beam-Column Calculation Spreadsheet (Excel)

Product Overview

This AISC 360-22 Steel Beam-Column Calculation Spreadsheet is an Excel-based engineering tool for verifying steel members subjected to combined axial compression and bending. It follows AISC 360-22 Chapter H, including beam-column interaction equations, corrosion assessment, strengthening (built-up sections), and stepped member evaluation. The spreadsheet is suitable for new design, structural assessment, and retrofit of steel structures.

FAQ

How do you check beam-column interaction in AISC 360-22?

Answer:
Beam-column interaction is checked using AISC 360-22 Chapter H equations H1-1a and H1-1b, comparing applied axial force and moments with available strength.

Can it be used for stepped columns or beams?

Answer:
Yes. The spreadsheet applies modified effective length factors (K) and moment gradient factors (Cb) for stepped or non-prismatic steel members.

Can this spreadsheet evaluate existing or corroded steel members?

Answer:
Yes. The spreadsheet includes a corrosion module that reduces section properties and re-checks axial and flexural strength based on section loss.

Does this spreadsheet follow AISC 360-22?

Answer:
Yes. All calculations are based on AISC 360-22, including beam-column interaction equations (H1-1a and H1-1b) and LRFD strength checks.
