Looking for something specific? Use the AI assistant in this documentation site. Ask in plain language, for example “How do I analyze a portal frame?” or “How do I link analysis results to a design calculator?” It searches our guides and worked examples for you.
Available in all regions: The Analysis Calculators (beam analysis, portal frames, trusses, custom cross sections, and more) are available no matter which region you work in: United States, Australia & New Zealand, Canada, and Europe.
Beam Analysis
Beam analysis calculators for moment, shear and deflection, with or without load combinations.
Cross-Sections
Calculate section properties for custom and thin-walled sections, and look up standard sections.
Diaphragm Analysis
Analyze flexible diaphragms and link diaphragm results to your calculations.
Sign and Axis Conventions
Truss Analysis
Analyze a Truss
Solve 2D roof, floor and custom trusses with a live FEA engine. Set nodes, fixities and members in the browser and see results as you work.
Create and Use a Custom Section in the Custom Truss Analysis
Learn how to build a custom truss layout, define member types, create a custom cross-section, and link it into the Custom Truss Analysis calculator.
Portal Frames
Analyze a Portal Frame
Analyze single- or multi-bay 2D portal frames with FEA. Flat, gable, arch and tied geometries, with moment, shear, axial and displacement results.
Portal Frame Analysis: Worked Examples
Worked examples for the Portal Frame Analysis calculator: common frame types, loads, reactions, and moment, shear, axial and displacement results.
