How do you calculate thermal expansion in steel structures?

Linear thermal expansion (ΔL) = α × L₀ × ΔT, where α is the coefficient of linear expansion (12.0 × 10⁻⁶ / °C for structural steel), L₀ is original length, and ΔT is temperature change. A 100-meter continuous welded steel rail experiencing a 40°C temperature swing expands by 12.0 × 10⁻⁶ × 100m × 40°C = 0.048 meters (48 mm or 1.89 inches).

Why does reinforced concrete use steel rebar instead of aluminum?

Steel and concrete have almost identical thermal expansion coefficients (~12.0 × 10⁻⁶ / °C). If aluminum (23.1 × 10⁻⁶ / °C) were used inside concrete, seasonal temperature swings would cause the metal to expand twice as much as the surrounding concrete, fracturing the structure.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (kelvin (K)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 T_tp = 1 kelvin (K)

2. Target SI Bridge (k_target):1 °F = 1 kelvin (K)

Step-by-step substitution for Triple Point of Water → Fahrenheit:V(°F) = V(T_tp) × ( 1 / 1 ) = V(T_tp) × 33.8

Mathematical FormulaValue in Fahrenheit = Value in Triple Point of Water × 33.8Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 8 T_tp, applying the conversion factor yields exactly 46.4 °F. At larger operational scale, 100 Triple Point of Water corresponds to 212 °F.
