TheStructuralCalc Makes Engineering Calculations Show Their Work

Field notes

The calculators run in the browser and update results and diagrams as inputs change, while the page also renders complete HTML on the server. The listed beam tool covers thirteen standard load cases, and the steel tool compares AISC W-shapes under LRFD or ASD, returning the lightest passing option plus heavier alternatives. The site says each calculator is checked against a published example before release and identifies omitted checks rather than implying that the result is a complete design.
