Profile overview for IPEAA 120

The IPEAA 120 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 117 mm and a flange width (b) of 64 mm, supported by a 3.8 mm thick web and 4.8 mm thick flanges. With a cross-sectional area of 1070 mm² and a linear mass of 8.4 kg/m, the IPEAA 120 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 2441000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 47610 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 210700 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the IPEAA 120 provides a y-axis shear area (at strong bending axis) of 614.4 mm² for web shear verification and a torsion constant of 8890 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 660000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
