Are these calculators free?

Yes. All calculators are free and run entirely in your browser. No account needed.

Which design codes are supported?

AISC 360, AS 4100, EN 1993, and CSA S16. Select the applicable code from the dropdown in each calculator.

Do calculators work offline?

After the first visit, the WASM engine is cached by your browser and most functionality is available offline.

How do I report a calculation error?

Use the feedback link in the site footer. Include your inputs, the expected result, and the standard clause reference.

Can I use calculator results in a professional report?

Results must be independently verified by a qualified engineer before use in any project. The calculators are educational tools, not design certifications.

Tools Directory

Directory of steel calculators (connections, beams, columns, loads, utilities) with documentation and verification notes.

This page is a hub page (sometimes called a directory or category landing page). Hub pages are essential for SEO and usability because they:

Provide a single, canonical index of related pages.
Help crawlers discover deep pages without relying on client-side navigation.
Concentrate and distribute internal link equity to the most important tools and references.
Reduce duplicate/thin signals by ensuring each category has a substantial unique introduction.

The links below are intentionally plain HTML links so they remain discoverable if scripts do not run.

What you’ll find here

A structured directory of steel calculators directory.
Short descriptions of what each page covers, plus the limitations.
Verification and documentation links so you can use calculators responsibly.
Cross-links to standards coverage to clarify terminology differences.

Connection calculators

Member and analysis calculators

Loads, utilities, and drafting aids

SEO and crawlability notes (implementation)

For this hub to work as an SEO asset, the server must return an HTML response that includes:

A unique <title> and <meta name="description">.
A visible <h1> and unique explanatory text.
Plain <a href="..."> internal links to the listed pages.
Breadcrumb schema and (optionally) FAQ schema.

Do not render the directory links only after JavaScript runs, or crawlers may treat the hub as thin content.

FAQ

Why not just show a navigation menu?
Menus are useful, but hub pages add unique explanatory text and organized link blocks. This reduces thin/duplicate signals and improves crawl paths.

Do these calculators follow every clause of every standard?
No. Standards are extensive and context-dependent. The calculators support educational workflows and screening checks; final design requires full code compliance verification.

Is this site a substitute for engineering software?
No. Treat it as a fast toolset for early iteration and learning. Use validated analysis/design software and professional review for real projects.

How should I link to results?
Link to the clean route (no query parameters). If you share inputs, do it in a controlled way that does not generate infinite indexable URL variants.

Where is the verification guide?
Use the verification guide for a QA workflow that applies to any calculator result.

Can I request additional calculators? Use the feedback link in the footer to suggest a new calculator. Priority is based on user demand and engineering safety impact.
