Profile overview for UBP 254x254x71

The UBP 254x254x71 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 249.7 mm and a flange width (b) of 258 mm, supported by a 12 mm thick web and 12 mm thick flanges. With a cross-sectional area of 9040 mm² and a linear mass of 71 kg/m, the UBP 254x254x71 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 100700000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 904600 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 34390000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UBP 254x254x71 provides a y-axis shear area (at strong bending axis) of 6192 mm² for web shear verification and a torsion constant of 486400 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 485100000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
