Beam Calculator

Comprehensive Beam Analysis with Visual Results

Quickly analyze statically indeterminate or determinate beams and members. Generate detailed bending moment, shear force, deflection, and reaction force diagrams.

Covers a wide range of support conditions including pinned, roller, fixed supports, and springs with user-defined vertical or lateral stiffness.

Apply point loads, distributed loads, in either the horizontal or vertical direction, and moments.

Download a visual, comprehensive PDF report with all diagrams and calculation results — perfect for documentation or engineering design records.

Beam Calculator – Structural Analysis Made Simple

This online beam calculator is designed for engineers, students, and professionals who need fast and accurate structural analysis. It supports a wide range of materials including steel, concrete, wood, or any custom-defined section.

  • Generate bending moment and shear force diagrams
  • Calculate reaction forces and deflection
  • Analyze determinate and indeterminate beams
  • Use standard or general section properties

Define the beam geometry, support conditions, and apply point loads, distributed loads, or moment loads. The calculator provides instant results and visual diagrams — all directly in your browser.

It includes built-in support for standard Australian and New Zealand steel sections, but is flexible enough for engineers worldwide — simply input any general or custom section shape to suit your region’s standards.

Once your analysis is complete, export a comprehensive PDF report featuring clear visual diagrams and detailed results — ideal for documentation, client submission, or project records.

Whether you're designing in steel, checking timber joists, or evaluating concrete spans, this powerful tool delivers accurate beam analysis for any project.
