Profile overview for UPN 100

The UPN 100 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 100 mm and a flange width (b) of 50 mm, supported by a 6 mm thick web and 8.5 mm thick flanges. With a cross-sectional area of 1350 mm² and a linear mass of 10.6 kg/m, the UPN 100 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 2060000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 49000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 293000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UPN 100 provides a y-axis shear area (at strong bending axis) of 850 mm² for web shear verification and a torsion constant of 28100 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 410000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
