HL 1100R

The HL 1100R 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 1118 mm and a flange width (b) of 405 mm, supported by a 26 mm thick web and 45 mm thick flanges. With a cross-sectional area of 63520 mm² and a linear mass of 499 kg/m, the HL 1100R 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 13050200000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 26810000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (I_z) provides 500000000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the HL 1100R provides a y-axis shear area (at strong bending axis) of 36450 mm² for web shear verification and a torsion constant of 32530000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 143400000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
