W14x176 Section Properties
Complete geometric properties for the W14x176 (Wide Flange) per AISC Steel Construction Manual, 16th Edition. This section weighs 176.0 lb/ft. Wide flange shapes are the most commonly used structural steel members in building construction. They have an I-shaped cross section with parallel flanges and are designated by their nominal depth and weight per foot.

About Wide Flange Shapes
Wide flange shapes are the most commonly used structural steel members in building construction. They have an I-shaped cross section with parallel flanges and are designated by their nominal depth and weight per foot.
How to Use This Data
The properties listed above are used in structural engineering calculations including:
- Moment of Inertia (I) — used to calculate deflection and stiffness. Higher I = less deflection under load.
- Section Modulus (S) — used to calculate bending stress. σ = M/S, where M is the bending moment.
- Plastic Section Modulus (Z) — used in LRFD design to calculate plastic moment capacity. Mp = Fy × Z.
- Radius of Gyration (r) — used in column buckling calculations. Higher r = more resistance to buckling.
- Torsional Constant (J) — used to calculate torsional resistance and lateral-torsional buckling.
- Area (A) — used to calculate axial capacity and self-weight.
