Profile overview for UB 533x210x109

The UB 533x210x109 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 539.5 mm and a flange width (b) of 210.8 mm, supported by a 11.6 mm thick web and 18.8 mm thick flanges. With a cross-sectional area of 13890 mm² and a linear mass of 109 kg/m, the UB 533x210x109 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 668600000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 2830000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 29420000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UB 533x210x109 provides a y-axis shear area (at strong bending axis) of 7926.08 mm² for web shear verification and a torsion constant of 1267000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 1989000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
