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 for Beam and Column Calculators

Which direction is positive for loads, shear, moment, deflection and reactions in Calcs.com beam and column calculators, and which axis is strong.

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.
