Profile overview for UB 1000x400x883

The UB 1000x400x883 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 1092 mm and a flange width (b) of 424 mm, supported by a 45.5 mm thick web and 82 mm thick flanges. With a cross-sectional area of 112530 mm² and a linear mass of 883 kg/m, the UB 1000x400x883 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 20964100000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 45260000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 1049700000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 1000x400x883 provides a y-axis shear area (at strong bending axis) of 69536 mm² for web shear verification and a torsion constant of 185100000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 265670000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
