This tool calculates member capacities for purlins and girts according to the American Iron and Steel Institute (AISI) S100-16 standards. The purlins are produced by AEP. Note that: (1) it uses section sizes listed in AEP's catalog, (2) Measurements are in imperial units, and (3) The webs do not include transverse stiffeners.

The Steel Purlin and Girts to AISI tool calculates the member capacities of purlins and girts following the American Iron and Steel Institute (AISI) S100-16 standards. It uses section sizes from AEP's catalog, measures all inputs and outputs in imperial units, and assumes that webs do not include transverse stiffeners. This tool simplifies compliance with AISI standards, providing reliable and efficient calculations for your structural design needs.
This tool is for:
- Structural Engineers who need accurate capacity checks for purlins and girts in steel building systems.
- Steel Fabricators and Manufacturers validating their product designs against AISI standards.
- Construction Professionals ensuring design conformance for lightweight steel structures during project planning.
Creating a parametric technical document with the Steel Purlin and Girts to AISI tool ensures clarity and precision in your design outputs. These reports enable streamlined communication with stakeholders, reduce errors, and enhance documentation for compliance with structural design standards.

FAQs
How does the absence of transverse stiffeners affect capacity?
Without transverse stiffeners, the web may have reduced resistance to buckling under load, affecting the member's capacity.
Can this tool be used for custom purlin or girt designs?
The tool is designed for section sizes in AEP's catalog. Custom designs may require additional analysis or software tailored to non-standard sections.
What are the advantages of cold-formed steel in construction?
Cold-formed steel is lightweight, versatile, and cost-effective, making it an excellent choice for purlins, girts, and other structural applications.

How to prepare an engineering report
Engineering reports require a balance of clarity, precision, and professionalism. Here are some best practices for preparing a report we use at CalcTree:
- Clear and visual: Use heading types to establish a logical structure, add diagrams for clarity.
- Integrate sources: Map data from your calculation tools such as spreadsheet or Python to your report.
- Units: Assign units to physical quantities.
- Compliance: State and hyperlink the relevant codes of practices.
- Peer review: Share a link to your page with team members for reviews and feedback.
