Profile overview for UB 760x380x434

The UB 760x380x434 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 813 mm and a flange width (b) of 387 mm, supported by a 25.9 mm thick web and 47 mm thick flanges. With a cross-sectional area of 55343.46 mm² and a linear mass of 434 kg/m, the UB 760x380x434 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 6188400000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 17400000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 455100000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 760x380x434 provides a y-axis shear area (at strong bending axis) of 36378 mm² for web shear verification and a torsion constant of 31270000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 66600000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
