Beam Deflection Calculator — Structural Engineering
Compute max deflection and slope of a simply supported beam under a central load.
Welcome to the Beam Deflection Calculator guide — a free online engineering tool, with no sign-up required.
What is Beam Deflection?
It is how much a beam bends under a load. This tool computes max deflection and slope.
How to Use
- Open the Beam Deflection Calculator
- Enter the central load in newtons
- Enter beam length, elastic modulus, and moment of inertia
- See deflection in mm and slope in radians
Why It Matters
Engineers check deflection to keep structures safe and within building code limits.
Useful Tips
- Use consistent SI units
- Steel E is about 200 GPa
- Deflection limit is often L/360
FAQ
What is the formula?
For a central load on a simply supported beam: δ = PL³/48EI.
