CHS 762/40

The CHS 762/40 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 circular hollow section features a nominal outer diameter of 762 mm and a uniform wall thickness of 40 mm. With a cross-sectional area of 90729.19584 mm² and a linear mass of 712.2241873 kg/m, the CHS 762/40 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 5930105604 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 20872693.33 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 5930105604 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the CHS 762/40 provides a y-axis shear area (at strong bending axis) of 57760 mm² for web shear verification and a torsion constant of 11860211209 mm⁴ for calculating rotational twist under eccentric loading.
