Profile overview for UC 305x305x240

The UC 305x305x240 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 352.5 mm and a flange width (b) of 318.4 mm, supported by a 23 mm thick web and 37.7 mm thick flanges. With a cross-sectional area of 30580 mm² and a linear mass of 240 kg/m, the UC 305x305x240 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 644500000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 4266000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 203100000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the UC 305x305x240 provides a y-axis shear area (at strong bending axis) of 24007.36 mm² for web shear verification and a torsion constant of 13060000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 5024000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
