Profile overview for UB 610x325x455

The UB 610x325x455 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 689 mm and a flange width (b) of 340 mm, supported by a 32 mm thick web and 57.9 mm thick flanges. With a cross-sectional area of 58057.76 mm² and a linear mass of 455 kg/m, the UB 610x325x455 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 4460800000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 15140000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 380900000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 610x325x455 provides a y-axis shear area (at strong bending axis) of 39372 mm² for web shear verification and a torsion constant of 50040000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 37760000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
