Structural Calculator
Calculate structural engineering parameters including stress, deflection, buckling, and load analysis
Structural Calculator
Calculate stress, strain, and safety factors using material properties and applied loads.
Structural Engineering Formulas
Essential formulas for structural analysis and design
Basic Mechanics
Stress & Strain
σ = F/A, ε = σ/E, σ_allow = σ_yield/SF
Beam Deflection
δ = PL³/(48EI) (point load), δ = 5wL⁴/(384EI) (uniform)
Column Buckling
P_cr = π²EI/(KL)² (Euler's formula)
Section Properties
Rectangle
A = bh, I = bh³/12, S = bh²/6
Circle
A = πr², I = πd⁴/64, S = πd³/32
Load Combinations
Ultimate: 1.2D + 1.6L, Wind: 1.2D + 1.0L + 1.0W
Design Principles
• Use appropriate safety factors
• Consider all load combinations
• Check serviceability limits
