Structural Analysis Tool

Run structural engineering calculations with real physics.

Built-in Helper Functions

• beam_deflection_simply_supported(F, L, E, I, x) — Point load deflection
• beam_max_stress(M, c, I) — Maximum bending stress σ = Mc/I
• safety_factor(strength, stress) — Factor of safety
• euler_buckling(E, I, L, K) — Critical buckling load
• moment_of_inertia_rect(b, h) — I = bh³/12
• moment_of_inertia_circle(d) — I = πd⁴/64

Usage

python3 /workspace/bridge.py structural_analysis '
F = 5000  # 5kN load
L = 1.5   # 1.5m span
E = 200e9 # Steel
b, h = 0.04, 0.08  # 40x80mm beam
I = moment_of_inertia_rect(b, h)
delta = beam_deflection_simply_supported(F, L, E, I)
sigma = beam_max_stress(F*L/4, h/2, I)
sf = safety_factor(250e6, sigma)
print(f"Deflection: {delta*1000:.3f} mm")
print(f"Max stress: {sigma/1e6:.1f} MPa")
print(f"Safety factor: {sf:.2f}")
'

Always use SI units: meters, Newtons, Pascals. Always compute and report safety factors.
