Profile overview for SHS 400/16

The SHS 400/16 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 400 mm, a width of 400 mm, and a uniform wall thickness of 16 mm. With a cross-sectional area of 23477.2386 mm² and a linear mass of 184.296323 kg/m, the SHS 400/16 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 561500000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 3322000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 561500000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the SHS 400/16 provides a y-axis shear area (at strong bending axis) of 11738.6193 mm² for web shear verification and a torsion constant of 932800000 mm⁴ for calculating rotational twist under eccentric loading.
