CHS 610/30

The CHS 610/30 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 610 mm and a uniform wall thickness of 30 mm. With a cross-sectional area of 54663.71217 mm² and a linear mass of 429.1101406 kg/m, the CHS 610/30 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 2304758764 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 10101000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 2304758764 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the CHS 610/30 provides a y-axis shear area (at strong bending axis) of 34800 mm² for web shear verification and a torsion constant of 4609517529 mm⁴ for calculating rotational twist under eccentric loading.
