Profile overview for CHS 1219/10

The CHS 1219/10 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 1219 mm and a uniform wall thickness of 10 mm. With a cross-sectional area of 37981.85518 mm² and a linear mass of 298.1575632 kg/m, the CHS 1219/10 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 6940144281 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 14617143.33 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 6940144281 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the CHS 1219/10 provides a y-axis shear area (at strong bending axis) of 24180 mm² for web shear verification and a torsion constant of 13880288562 mm⁴ for calculating rotational twist under eccentric loading.
