HEA 450

The HEA 450 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 440 mm and a flange width (b) of 300 mm, supported by a 11.5 mm thick web and 21 mm thick flanges. With a cross-sectional area of 17800 mm² and a linear mass of 140 kg/m, the HEA 450 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 (I_y) of 637200000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 3215000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 94650000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HEA 450 provides a y-axis shear area (at strong bending axis) of 12600 mm² for web shear verification and a torsion constant of 2501000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 4147000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
