CHS 762/25

The CHS 762/25 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 25 mm. With a cross-sectional area of 57883.84464 mm² and a linear mass of 454.3881804 kg/m, the CHS 762/25 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 3934610927 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 13584433.33 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 3934610927 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the CHS 762/25 provides a y-axis shear area (at strong bending axis) of 36850 mm² for web shear verification and a torsion constant of 7869221853 mm⁴ for calculating rotational twist under eccentric loading.
