Profile overview for UB 457x152x74

The UB 457x152x74 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 462 mm and a flange width (b) of 154.4 mm, supported by a 9.6 mm thick web and 17 mm thick flanges. With a cross-sectional area of 9450 mm² and a linear mass of 74.2 kg/m, the UB 457x152x74 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 326500000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 1625000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 10460000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 457x152x74 provides a y-axis shear area (at strong bending axis) of 5249.6 mm² for web shear verification and a torsion constant of 657700 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 516200000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
