Profile overview for W 1000x400x371

The W 1000x400x371 is a structural steel cross-section utilized in commercial construction, industrial framing, and mechanical engineering. Manufactured as a hot rolled section, it complies with ASTM A 6/A 6M 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 1000 mm and a flange width (b) of 400 mm, supported by a 19 mm thick web and 36.1 mm thick flanges. With a cross-sectional area of 47300 mm² and a linear mass of 371 kg/m, the W 1000x400x371 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 8137300000 mm⁴ governs major deflection and serviceability limits. To calculate the ultimate bending resistance, engineers may utilize the strong-axis plastic section modulus of 18360000 mm³. For lateral stability and column buckling verifications, the weak-axis moment of inertia (Iz) provides 385800000 mm⁴ of lateral stiffness.

Advanced analysis: For complex load cases, the W 1000x400x371 provides a y-axis shear area (at strong bending axis) of 28880 mm² for web shear verification and a torsion constant of 15880000 mm⁴ for calculating rotational twist under eccentric loading. Additionally, a warping constant of 89440000000000 mm⁶ is available for rigorous lateral-torsional buckling (LTB) checks.
