Profile overview for CHS 1016/12
The CHS 1016/12 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 circular hollow section features a nominal outer diameter of 1016 mm and a uniform wall thickness of 12 mm. With a cross-sectional area of 37849.90829 mm² and a linear mass of 297.1217801 kg/m, the CHS 1016/12 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 4769845443 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 12096768 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 4769845443 mm⁴ of lateral stiffness.
Advanced analysis: For complex load cases, the CHS 1016/12 provides a y-axis shear area (at strong bending axis) of 24096 mm² for web shear verification and a torsion constant of 9539690886 mm⁴ for calculating rotational twist under eccentric loading.
