Free structural calculators, validated against independent reference solutions and shared for educational purposes.
Open Simply Supported Beam AnalysisMore calculators are on the way. Every tool here is validated before it's published — see each tool's page for its validation report.
Analyze simply-supported beams under point loads, UDLs, and applied moments — reactions, shear, bending moment, and deflection diagrams, with a downloadable PDF report.
Open toolArea, centroid, moments of inertia, elastic and plastic moduli, radii of gyration, torsion and warping constants — starting with built-up I-sections, with more shapes on the way.
Open toolAdditional structural calculators are planned for this platform. Check back soon.
