Profile overview for HD 400x382

The HD 400x382 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 416 mm and a flange width (b) of 406 mm, supported by a 29.8 mm thick web and 48 mm thick flanges. With a cross-sectional area of 48710 mm² and a linear mass of 382 kg/m, the HD 400x382 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 1416700000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 7987000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 536200000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HD 400x382 provides a y-axis shear area (at strong bending axis) of 38976 mm² for web shear verification and a torsion constant of 33480000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 18120000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
