Profile overview for SHS 220/8

The SHS 220/8 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a cold formed section, it complies with EN 10219-2 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 rectangular/square hollow section is defined by a depth of 220 mm, a width of 220 mm, and a uniform wall thickness of 8 mm. With a cross-sectional area of 6564.247719 mm² and a linear mass of 51.5293446 kg/m, the SHS 220/8 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 48280000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 515600 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 48280000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the SHS 220/8 provides a y-axis shear area (at strong bending axis) of 3282.12386 mm² for web shear verification and a torsion constant of 78150000 mm⁴ for calculating rotational twist under eccentric loading.
