2026 CFSEI EXPO | MAY 18-20, 2026 | LONG BEACH, CALIFORNIA

A Web-Based App for Cold-Formed Steel Member Structural Calculations Built with Open-Source Software

Imagine your company has developed a new family of cold-formed steel cross-sections. You are pretty sure they work better than the industry baseline, however you don’t quite have the right workflow tool to calculate and tabulate section and buckling properties that confirm improved structural performance. In this presentation, we will introduce a web-based app that can quickly generate these results for you, graphically and in tabular formats, for multiple cross-sections at once. We will introduce the app, show how anyone can access it, and provide a demo for how it works. This web app is a prototype, a glimpse into the future, of what can be done by our industry to advance engineering workflows with freely available, open-source software.

Learning Objectives

  • Highlight how software can accelerate engineering workflows in cold-formed steel
  • Demonstrate the use of open-source software packages available for cold-formed steel design
  • Explore user interface needs for modern CFS engineering workflows
  • Show how advanced analysis can make things cleaner and simpler to design cold-formed steel members
