Overview

The Beam Analysis Tool is a Python-based engineering application for structural analysis of simply supported beams under common loading conditions.

The tool computes reaction forces, generates Shear Force Diagrams (SFD) and Bending Moment Diagrams (BMD), and plots the deflection curve using numerical methods. A browser-based GUI built with Chart.js is also included for interactive use.

Example

Input:

• Beam Length: 5 m
• E = 200 GPa, I = 8.33 × 10⁶ mm⁴
• Point Load: 10 kN at 2 m from LHS

Output:

• R₁ = 6,000 N, R₂ = 4,000 N
• Max Bending Moment = 12,000 Nm at x = 2.000 m
• Max Deflection = 3.835 mm — within L/250 serviceability limit (20 mm)
