- 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 design guides and checklists.
- 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.

How to use guides responsibly
These guides are written as process documentation and QA checklists, not as engineering advice for any specific project.
They aim to surface assumptions, common sources of error, and the minimum documentation you should keep so results can be reviewed.
If you are working on a real project, a qualified engineer should define the governing criteria and verify compliance.
Guide descriptions and educational pathways
Verification and checklists
The How to Verify Structural Calculations guide is the entry point for anyone using the site's calculators. It presents a systematic QA workflow: identify inputs and assumptions, run an independent check (hand calculation, alternative method, or validated software), compare results within an acceptable tolerance, document the verification, and retain an audit trail. This process applies to every calculator on the site regardless of design standard.
The Bolted Connection Design Checklist provides a methodical walk-through of bolt group verification. It covers bolt shear capacity per bolt, combined shear and tension interaction (AISC 360 Equation J3-3a and J3-3b), bearing strength at bolt holes (AISC 360 Equation J3-6a), block shear rupture (AISC 360 Equation J4-5), bolt spacing and edge distance requirements per AISC 360 Table J3.4, and prying action in tension connections. The checklist follows both LRFD and ASD methodology and references equivalent AS 4100, EN 1993, and CSA S16 clauses where applicable.
The Weld Design Checklist covers fillet weld and groove weld design. It addresses weld throat area calculation, directional strength increase for fillet welds per AISC 360 Equation J2-5, minimum weld size per AWS D1.1 Table 7.1, maximum weld size limitations, electrode strength selection (E70XX, E80XX, etc.), and weld inspection category requirements. It also includes prequalified weld joint details and their limitations.
The Base Plate Design Checklist guides users through base plate verification: concrete bearing strength per AISC 360 Equation J8-1 or equivalent, plate bending moment and thickness determination using the cantilever method, anchor bolt tension capacity per AISC 360 Chapter J or CSA S16 Clause 25, anchor bolt shear capacity including edge distance effects, grout pad and leveling plate considerations, and stiffener plate design for heavily loaded plates.
Design workflows
The Steel Beam Design Workflow follows the AISC 360 Chapter F design process from beginning to end. It starts with load takedown and required strength determination, proceeds through section classification (compact, non-compact, slender), nominal flexural strength Mn calculation including lateral-torsional buckling, flange local buckling, and web local buckling limit states, nominal shear strength Vn per AISC 360 Chapter G, deflection serviceability checks, and interaction checks for combined flexure and axial load where applicable.
The Column Buckling Design Workflow presents the AISC 360 Chapter E column design process. It covers effective length factor K determination based on end restraint conditions, slenderness ratio KL/r, elastic critical buckling stress Fe, flexural buckling stress Fcr for elastic and inelastic buckling per AISC 360 Equations E3-2 through E3-4, torsional and flexural-torsional buckling considerations, and interaction with moment when applicable per AISC 360 Chapter H.
The Deflection Limits Explained guide provides context for serviceability criteria used in structural steel design. It covers L/360 limits typical for roof live load deflection, L/240 for total load on roof members, L/600 for crane runway beams supporting bridge cranes with heavy service, L/120 for wind drift limits in building frames, and L/360 for wind drift limits with masonry cladding. The guide explains the origin of these limits, their application in different standards, and how to apply them to specific design situations.
The Wind Load Calculation Workflow guides you through the ASCE 7-22 wind load determination process: determining the basic wind speed from the wind speed map or ASCE 7 figures, selecting the exposure category (B, C, or D) based on terrain, calculating the velocity pressure exposure coefficient Kz, determining the topographic factor Kzt, computing the velocity pressure qz, selecting the appropriate gust effect factor G, and calculating design wind pressures for the main wind force resisting system (MWFRS) and components and cladding (C&C).
Worked examples
The AS 4100 Base Plate Design Guide presents a complete worked example following AS 4100-2020 Clause 7 and the Australian Steel Institute design procedures. It covers bearing area and concrete bearing capacity, base plate bending moments about critical sections, required plate thickness, anchor bolt design for tension and shear with combined interaction, and typical detailing requirements including grout thickness and leveling nuts.
The AISC 360 Bolted Shear Tab Worked Example works through a complete single-plate (shear tab) connection design. It covers bolt shear capacity for the specified bolt grade and diameter, bearing strength of the plate material at bolt holes, plate gross section and net section yielding, block shear rupture of the extended tab plate, weld design for the plate-to-supporting-member connection, and detailing checks including edge distance and bolt spacing.
The AS 4100 Base Plate Worked Example with Calculations provides a detailed numerical example showing axial compression combined with bending moment interaction for a base plate designed to AS 4100. Each calculation step is shown with the relevant AS 4100 clause reference, the formula applied, and the resulting value.
How to choose and follow a guide
Selecting the right guide depends on your current design task. If you are verifying a specific connection or member design, use the corresponding checklist to ensure no limit state is missed. If you are learning a new design process, follow the workflow guides from start to finish. If you need to see a complete numerical example for a specific standard, study the worked examples in the applicable standard.
All guides are designed to be used alongside the site's calculators. Read the relevant guide to understand the design procedure, then run the calculator with your specific inputs, and use the checklist to verify the outputs. This approach reinforces learning and reduces the chance of overlooking critical limit states.
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.
How often are guides updated? Guides are reviewed when standards are revised or when user feedback identifies a gap.
Which guide should I start with as a new user? Start with the How to Verify Structural Calculations guide to establish your QA workflow. Then follow the design workflow guide for your specific task (beam design, column buckling, or connection design). Use the checklists during verification and the worked examples to see the complete process in action.
