![]() Modulus of elasticity of structural steel The unit weight of structural steel is specified in the design standard EN Table A.4 between 77.0 kN/m 3 and 78.5 kN/m 3.įor structural design it is standard practice to consider the unit weight of structural steel equal to γ = 78.5 kN/m 3 and the density of structural steel approximately ρ = 7850 kg/m 3.

The steel classes are defined in the corresponding standards:ĮN 10025-2 Hot rolled products of structural steels. For the purpose of structural design appropriate material safety factors are applicable, such as the factors γ M0, γ M1, γ M2 etc. The provided values for f y and f u are nominal values. ĭesign values of structural steel material properties Nominal values of structural steel yield strength and ultimate strengthįor structural design according to Eurocode 3 (EN), the nominal values of the yield strength f y and the ultimate strength f u for structural steel are obtained as a simplification from EN Table 3.1, which is reproduced above in tabular format. Sub-grade J2 correspond to a minimum KV of 27 J at -20☌. Sub-grade J0 correspond to a minimum KV of 27 J at 0☌. Sub-grade JR correspond to a minimum KV of 27 J at Room temperature (+20☌). the impact energy in Joules required to fracture a Charpy V-notch specimen at a given test temperature T. The fracture toughness of steel is characterized in EN in terms of the KV(T) value i.e. Steel sub-grades JR, J0, J2, K2 characterize the ability of steel to behave in a ductile manner and therefore avoid brittle fracture, especially at low temperatures.See Details below for the description of the relevant EN standard. Steel grades with the designation 'H', according to the standard EN 10219-1 are applicable for cold formed structural hollow sections. ![]() ![]() Steel grades with the designation 'H', according to the standard EN 10210-1 are applicable for hot finished structural hollow sections.
