Profile overview for UB 254x102x22

The UB 254x102x22 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 254 mm and a flange width (b) of 101.6 mm, supported by a 5.7 mm thick web and 6.8 mm thick flanges. With a cross-sectional area of 2800 mm² and a linear mass of 22 kg/m, the UB 254x102x22 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 28480000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 259600 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 1193000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 254x102x22 provides a y-axis shear area (at strong bending axis) of 1381.76 mm² for web shear verification and a torsion constant of 42030 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 18150000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
