Structural Engineering Fundamentals
Essential calculations for safe and efficient structural design:
Beam Stiffness Formula
I = (b × d³) / 12
δ = (5 × w × L⁴) / (384 × E × I)
Where:b = width, d = depth, L = length
w = uniform load, E = modulus of elasticity
I = moment of inertia, δ = deflection
Beam Analysis
Determines deflection, bending moments, and shear forces for structural members under load.
Load Calculations
Combines dead loads (permanent) and live loads (temporary) with safety factors for design.
Foundation Design
Ensures structural loads are properly transferred to the ground without exceeding soil capacity.
