Profile overview for RHS 160x80/10

The RHS 160x80/10 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 rectangular/square hollow section is defined by a depth of 160 mm, a width of 80 mm, and a uniform wall thickness of 10 mm. With a cross-sectional area of 4292.699082 mm² and a linear mass of 33.69768779 kg/m, the RHS 160x80/10 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 (Iy) of 12840000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 209000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 4112000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the RHS 160x80/10 provides a y-axis shear area (at strong bending axis) of 1430.899694 mm² for web shear verification and a torsion constant of 10410000 mm⁴ for calculating rotational twist under eccentric loading.
