Profile overview for UB 760x380x531

The UB 760x380x531 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 833 mm and a flange width (b) of 393 mm, supported by a 31.5 mm thick web and 56.9 mm thick flanges. With a cross-sectional area of 67721.56 mm² and a linear mass of 531 kg/m, the UB 760x380x531 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 7766400000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 21550000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 577600000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 760x380x531 provides a y-axis shear area (at strong bending axis) of 44723.4 mm² for web shear verification and a torsion constant of 55630000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 86670000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
