Profile overview for UB 1000x400x483

The UB 1000x400x483 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 1020 mm and a flange width (b) of 404 mm, supported by a 25.4 mm thick web and 46 mm thick flanges. With a cross-sectional area of 61510 mm² and a linear mass of 483 kg/m, the UB 1000x400x483 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 10674800000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 23920000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 507100000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 1000x400x483 provides a y-axis shear area (at strong bending axis) of 37168 mm² for web shear verification and a torsion constant of 33060000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 119890000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
