Profile overview for UB 914x305x238

The UB 914x305x238 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 915 mm and a flange width (b) of 305 mm, supported by a 16.5 mm thick web and 25.9 mm thick flanges. With a cross-sectional area of 30350 mm² and a linear mass of 238 kg/m, the UB 914x305x238 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 4070100000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 10240000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 122800000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 914x305x238 provides a y-axis shear area (at strong bending axis) of 15799 mm² for web shear verification and a torsion constant of 5183000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 24200000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
