Profile overview for HD 400x1086

The HD 400x1086 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 569 mm and a flange width (b) of 454 mm, supported by a 78 mm thick web and 125 mm thick flanges. With a cross-sectional area of 138580 mm² and a linear mass of 1086 kg/m, the HD 400x1086 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 5960700000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 27230000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 1962700000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HD 400x1086 provides a y-axis shear area (at strong bending axis) of 113500 mm² for web shear verification and a torsion constant of 612200000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 96070000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
