Profile overview for HEA 120

The HEA 120 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a hot rolled section, it complies with EN 10365 dimensional standards, ensuring predictability in detailing and fabrication.Access to its exact geometric and statical properties is essential for 3D modeling and structural verification.

Geometry: This open profile features a total depth (h) of 114 mm and a flange width (b) of 120 mm, supported by a 5 mm thick web and 8 mm thick flanges. With a cross-sectional area of 2530 mm² and a linear mass of 19.9 kg/m, the HEA 120 offers a distinct stiffness-to-weight ratio for both column (axial) and beam applications.

Section properties: For design of bending, the major and minor axis properties dictate the member's structural capacity. The strong-axis moment of inertia (Iy) of 6061000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 119400 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 2308000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HEA 120 provides a y-axis shear area (at strong bending axis) of 1920 mm² for web shear verification and a torsion constant of 60410 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 6471000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
