Profile overview for UB 914x305x474

The UB 914x305x474 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 971 mm and a flange width (b) of 316 mm, supported by a 30 mm thick web and 54.1 mm thick flanges. With a cross-sectional area of 60390 mm² and a linear mass of 474 kg/m, the UB 914x305x474 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 8862800000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 21400000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 286500000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 914x305x474 provides a y-axis shear area (at strong bending axis) of 34191.2 mm² for web shear verification and a torsion constant of 41180000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 59790000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
