According to IS 800:2007, the recommended values of the following physical properties: Unit mass (ρ), Modulus of Elasticity (E), and Poisson's ratio (μ) of structural steel (irrespective of the grade) for use in design, are to be taken as:
1
ρ = 7850 kg/m3 ; E = 2 × 105 MPa; μ = 0.3
2
ρ = 9850 kg/m3 ; E = 2 × 106 MPa ; μ = 0.4
3
ρ = 785 kg/m3 ; E = 2000 MPa ; μ = 0.25
4
ρ = 6850 kg/m3 ; E = 2 × 104 MPa ; μ = 0.2
