Profile overview for UB 457x279x213

The UB 457x279x213 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 495 mm and a flange width (b) of 285 mm, supported by a 18.5 mm thick web and 33.5 mm thick flanges. With a cross-sectional area of 27356.36 mm² and a linear mass of 213 kg/m, the UB 457x279x213 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 1154400000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 5325000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 129500000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 457x279x213 provides a y-axis shear area (at strong bending axis) of 19095 mm² for web shear verification and a torsion constant of 8430000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 6881000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
