IPEO 220

The IPEO 220 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 222 mm and a flange width (b) of 112 mm, supported by a 6.6 mm thick web and 10.2 mm thick flanges. With a cross-sectional area of 3740 mm² and a linear mass of 29.4 kg/m, the IPEO 220 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 31340000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 321100 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 2398000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the IPEO 220 provides a y-axis shear area (at strong bending axis) of 2284.8 mm² for web shear verification and a torsion constant of 121600 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 26780000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
