Parameter Description Unit Example Values
Steel Grade Designation of the steel type - Q235, Q345, ASTM A36
Yield Strength Stress at which the steel begins to deform plastically MPa 235 for Q235, 345 for Q345
Ultimate Tensile Strength Maximum stress the steel can withstand before failure MPa 370 - 500 for Q235, 470 - 630 for Q345
Elastic Modulus Measure of the steel's stiffness in the elastic range GPa 206 for carbon steel
Poisson's Ratio Ratio of lateral strain to axial strain under uniaxial stress - 0.3 for steel
Density Mass per unit volume of the steel kg/m³ 7850 for carbon steel
Cross-Section Shape Shape of the steel member cross-section - I-beam, H-beam, channel, angle
Cross-Section Dimensions Width, height, thickness, etc. of the cross-section mm For an I-beam: height = 300 mm, width = 150 mm, flange thickness = 10 mm, web thickness = 8 mm
Moment of Inertia Geometric property related to the cross-section's resistance to bending mm⁴ Varies depending on cross-section shape and dimensions
Section Modulus Geometric property related to the cross-section's resistance to bending stress mm³ Varies depending on cross-section shape and dimensions
Torsional Constant Property related to the cross-section's resistance to torsion mm⁴ Varies depending on cross-section shape and dimensions
Weld Strength Strength of the welded joint, related to the welding process and materials MPa Depends on welding method, electrode type, etc.
