Single Beam Calc - Calculator

Single Beam Calc is a free structural engineering beam calculator that makes beam analysis simple and accessible.
Analyze cantilever and simply supported beams quickly and clearly — from learning structural mechanics to practical design checks.

Instantly calculate bending moment, shear force, and deflection, and visualize beam behavior under load.

Have you ever thought:
"I understand the formulas, but can’t picture the behavior?"
"I want values not only at max/min points, but anywhere along the beam."
"I need results immediately."

This app is designed for those situations.
It runs lightweight and fast, completing calculations in seconds, and works fully offline — ideal for classrooms, offices, or field environments.

■ Key Features

- Bending moment, shear force, and deflection calculation
- Diagram visualization (moment and shear diagrams)
- Supports point loads, uniform loads, triangular loads, and applied moments
- Add or remove multiple load conditions
- Select support/boundary conditions (free end, simply supported, fixed)
- Unit selection (supports mm / cm / m, in / ft, N/mm² / MPa, etc.)

■ Highlights

- Completely free
- Lightweight and fast performance
- Offline capable
- Simple and intuitive interface
- Ideal for structural mechanics learning
- Useful for civil and architectural design support

From students to professionals, Single Beam Calc helps you understand beam behavior, verify calculations, and streamline pre-design evaluation.
