Profile overview for HEAA 260

The HEAA 260 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a hot rolled section, it complies with EN 10365 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 open profile features a total depth (h) of 244 mm and a flange width (b) of 260 mm, supported by a 6.5 mm thick web and 9.5 mm thick flanges. With a cross-sectional area of 6900 mm² and a linear mass of 54.1 kg/m, the HEAA 260 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 79800000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 714400 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 27880000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HEAA 260 provides a y-axis shear area (at strong bending axis) of 4940 mm² for web shear verification and a torsion constant of 300900 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 382500000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
