Mechanical properties of structural steel

1. Modulus of elasticity (E) = 2 x 105   N/mm2

2. Shear modulus (G) = 0.769 x 105  N/mm2

3. Poisson's ratio (µ) 

   a. Elastic range = 0.3

   b. Plastic range = 0.5

4. Coefficient of thermal expansion (α) = 12 x 10-6 / ֯C

5. Density of steel = 7850 Kg/m3
