Free Beam Load Calculator
Free Beam Load Calculator – PDF Export 2025
Are you working with beams in construction or engineering? This free online Beam Load Calculator helps you quickly calculate how a beam behaves under loads — and shows it in 3D!
Whether you’re a student, engineer, architect, or DIY builder, this tool lets you:
- Calculate support reactions
- View bending moment and shear force diagrams
- See deflection (bending) of the beam
- Export your results to PDF
- Switch between metric and imperial units
- Visualize the beam in a real-time 3D model
Why Use This Free Beam Load Calculator?
This tool saves you time and avoids manual errors. Instead of complex formulas, just enter your beam’s details — length, material, loads — and get instant results.
You can:
- Add multiple point loads at different positions
- Adjust material properties like Young’s Modulus (E) and Moment of Inertia (I)
- View accurate diagrams for shear force and bending moment
- Animate the deflection curve to see how your beam would bend (exaggerated for clarity)
Who Is It For?
- Engineers working with steel, concrete, or wood beams
- Civil engineering students or teachers
- Architects designing structural elements
- Anyone doing structural analysis or simple load checks
- Hobbyists and builders working on home projects
How to Use the Calculator
- Enter your beam’s total length
- Select the material or input Young’s Modulus (E)
- Add one or more point loads — set their values and positions
- Choose between metric (m, N) or imperial (ft, lb) units
- Click Calculate
- See support reactions, BMD, SFD, deflection
- Optionally export your results as a PDF

✅ Frequently Asked Questions (FAQ)
Simple, user-friendly answers for your visitors and SEO rich snippets.
❓What is a beam load calculator?
A beam load calculator is a tool that helps you determine how a beam reacts to forces. It calculates support reactions, bending moments, shear forces, and deflection based on beam length, material, and load positions.
❓Can this calculator show bending and shear diagrams?
Yes! It automatically generates Bending Moment Diagrams (BMD) and Shear Force Diagrams (SFD) for simply supported beams with point loads.
❓Does it work with both metric and imperial units?
Absolutely. You can switch between metric (meters, kilonewtons) and imperial (feet, pounds) with a simple toggle button.
❓Is the deflection shown accurate?
The deflection is calculated using standard structural engineering formulas. For better visual understanding, the deflection is shown in an exaggerated animated form — it’s not to scale but great for conceptual understanding.
❓Can I export the results?
Yes, with one click, you can export all results including diagrams and load setup to a PDF, making it ideal for reports, assignments, or project documentation.
❓Can I use this tool on my mobile phone?
Yes, the tool is fully mobile-friendly and responsive, with support for touch navigation and 3D rotation using your fingers.
❓Is this calculator free to use?
Yes! This is a completely free online tool designed to help engineers, students, and builders quickly understand beam behavior.
✅ Conclusion
Whether you’re designing a bridge, modeling a floor beam, or learning about structural mechanics in class, this tool gives you instant insights into how your beam will perform. From diagrams to deflection to live 3D visuals, it’s your all-in-one beam analysis solution — right in your browser.
