Resources
Downloadable-style resources: calculation note templates, unit checklists, and data provenance documentation.
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 engineering documentation resources.
- 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.
Templates and reference resources
Intended use
Resources are meant to be copied into your internal documentation workflow (for example, a calculation note format or QA checklist).
They are intentionally neutral and do not prescribe design criteria, because criteria are project- and jurisdiction-specific.
Resource descriptions and usage guidance
Each resource is designed to be adapted into your existing engineering documentation workflow. Understanding how to use them effectively helps maintain consistency and quality in your design records.
Calculation Note Template
The Calculation Note Template provides a structured format for recording structural engineering calculations. It includes sections for:
- Project information: Project name, number, date, engineer, reviewer, and revision history.
- Design criteria: Governing standard, material specifications, load criteria, and design parameters.
- Input parameters: Geometry, loads, material properties, and other calculation inputs organized in a clear tabular format.
- Calculation section: Numbered calculation steps with formulas, references, and intermediate values. Each step includes the formula or code clause reference, the calculation, the result, and a check box or status indicator.
- Results summary: A summary table showing the governing limit states, design capacities, demand-to-capacity ratios, and acceptance criteria.
- Verification section: Space for independent verification by a second engineer, including verification method, acceptable tolerance, comparison results, and sign-off.
To use the template, copy the structure into your internal documentation system or word processor. Adapt the section headings and format to match your firm's quality management system requirements. The template is designed to satisfy typical QA/QC documentation needs for structural engineering calculations under ISO 9001 or equivalent quality frameworks.
Unit Consistency Checklist
The Unit Consistency Checklist is a practical tool for preventing one of the most common sources of error in structural engineering calculations: unit mismatch. It covers:
- Force units: Checking consistency between kN, N, kips, and pounds throughout the calculation. Ensuring that when using AS 4100 or EN 1993 (metric), all force values are in kN or N, and when using AISC 360 (imperial), forces are in kips.
- Length units: Verifying that dimensions are consistently in mm (metric) or inches (imperial). Checking that section properties use the correct units -- moments of inertia in mm^4 or in^4, section moduli in mm^3 or in^3.
- Stress units: Confirming stress units match -- MPa (N/mm^2) for metric standards, ksi for imperial standards. Checking that yield strength Fy, tensile strength Fu, and calculated stresses are all in the same unit system.
- Moment units: Verifying moment units -- kN-m or N-mm for metric, kip-ft or kip-in for imperial. Ensuring conversion between units uses the correct factors.
- Conversion factors: Providing a quick reference for common unit conversions used in structural steel design, including kN to kips, MPa to ksi, mm to inches, and kN-m to kip-ft.
Use this checklist at the start of any calculation to verify unit consistency, and again at the end when reviewing outputs. The calculators on SteelCalculator.app handle unit conversion internally, but inputs must be in the correct unit system and outputs must be interpreted with the correct units.
Section Properties Data Sources
The Section Properties Data Sources page documents the provenance of all section property data used on the site. This is important for traceability and verification. It covers:
- Data origin: The official standard publications from which section dimensions and properties are sourced, including AISC Manual 15th Edition, BSI BS 4-1, EURONORM 19-57, AS/NZS 3679.1, and CISC Handbook of Steel Construction.
- Verification process: How the data is cross-checked against published values, the tolerance thresholds used during verification, and the date of the most recent verification cycle.
- Section families covered: A complete list of the section families included in the database, from American W-shapes to European IPE, HEA, HEB sections to British UB and UC to Australian and Canadian sections.
- Known limitations: Any gaps or known discrepancies in the data, such as sections that use outdated dimensional standards or proprietary sections where published data is limited.
- QA recommendations: Guidance on how users should verify section properties for their specific project, including cross-referencing against supplier mill certificates or the governing standard.
How to integrate resources into your workflow
The three resources work together as a documentation ecosystem. Start a new design task by copying the Calculation Note Template into your project folder. As you gather design criteria and standards, record them in the template's design criteria section. When you collect section properties and material data, note the source in the Section Properties Data Sources format. As you run calculations, fill in the calculation section with step-by-step entries. Before finalizing, run through the Unit Consistency Checklist to catch any unit errors.
This documentation workflow aligns with standard quality assurance practices for structural engineering and ensures that your calculation records are complete, traceable, and reviewable.
Navigation guidance for this hub
The resources hub collects downloadable-style content that supports your engineering documentation workflow. The Calculation Note Template is the primary resource for recording calculations. The Unit Consistency Checklist is a cross-cutting quality check that applies to all calculations regardless of standard or tool. The Section Properties Data Sources page provides the provenance documentation needed for traceability.
Each resource page includes instructions for adaptation and use. Bookmark the resources hub for easy access during your design workflow.
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.
Frequently Asked Questions
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 adapt the calculation note template for my firm? Yes. The template provides a starting structure. Adapt it to match your firm's quality system and documentation standards.
Are these resources compatible with ISO 9001 quality systems? Yes. The calculation note template and unit consistency checklist are designed to support documentation practices that satisfy typical QA/QC requirements, including those under ISO 9001. Adapt the format and approval workflows to match your specific quality management system.
