SHS 40/5

The SHS 40/5 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a hot finished section, it complies with EN 10210-2 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 40 mm, a width of 40 mm, and a uniform wall thickness of 5 mm. With a cross-sectional area of 673.1747704 mm² and a linear mass of 5.284421948 kg/m, the SHS 40/5 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 133700 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 8663 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 133700 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the SHS 40/5 provides a y-axis shear area (at strong bending axis) of 336.5873852 mm² for web shear verification and a torsion constant of 225000 mm⁴ for calculating rotational twist under eccentric loading.
