Profile overview for UB 457x279x286

The UB 457x279x286 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 517 mm and a flange width (b) of 291 mm, supported by a 24.4 mm thick web and 44.4 mm thick flanges. With a cross-sectional area of 36632.24 mm² and a linear mass of 286 kg/m, the UB 457x279x286 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 1621800000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 7296000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 182900000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 457x279x286 provides a y-axis shear area (at strong bending axis) of 25840.8 mm² for web shear verification and a torsion constant of 19420000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 10180000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
