Profile overview for UC 305x305x107

The UC 305x305x107 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 311 mm and a flange width (b) of 306 mm, supported by a 10.9 mm thick web and 17 mm thick flanges. With a cross-sectional area of 13770 mm² and a linear mass of 107 kg/m, the UC 305x305x107 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 250500000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 1784000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 81250000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UC 305x305x107 provides a y-axis shear area (at strong bending axis) of 10404 mm² for web shear verification and a torsion constant of 1298000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 1754000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
