Section Profile Summary
This is a standard hot-rolled bearing pile profile covered by AISC 360. The tabulated section properties are computed from the nominal dimensions per the governing material standard. With Ix = 1,220 in⁴, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.
At 14.2" deep and 117 lb/ft, this is a mid-range section suitable for floor beams, roof framing, and columns in low-to-mid-rise structures.

Design Notes
- Compactness: Verify flange and web slenderness against AISC 360 Table B4.1 classification limits for the governing load case (pure compression, pure flexure, or combined).
- Combined loading: For members under simultaneous axial force and bending, use the interaction equations in AISC 360 Section H. The governing equation depends on the ratio of required to available axial strength.
- Connection limit states: Check bolt bearing, tear-out, block shear, and weld strength at all connections. The governing connection limit state often controls the member size selection.
Verification (AISC 360): All designs using this section must be verified by a licensed Professional Engineer. Before finalizing member selection, check beam-column interaction (P-M), lateral-torsional buckling, serviceability deflections, and all connection limit states. See Engineering Disclaimer.
Worked Example: Bearing Pile Capacity — hp14x117
Scenario: hp14x117 driven to 60 ft depth in medium-dense sand. The pile carries axial compression from a column above. Pile capacity is governed by a combination of geotechnical end bearing + skin friction, plus the structural section capacity.
Given:
- hp14x117: Ag = 34.4 in²
- Steel: ASTM A572 Gr. 50, Fy = 50 ksi
- Unbraced length below ground: L = 60 ft (fully laterally supported by soil)
Structural capacity (AISC 360 Chapter E):
φPn = 0.9 × Fy × Ag = 0.9 × 50 × 34.4 = 1,548 kips
The structural capacity typically governs over geotechnical capacity for HP sections in dense soils. Driving stresses should also be checked per PDCA/AASHTO specifications — limit driving stress to 0.9Fy during hard driving conditions.
The final pile capacity must be confirmed by a geotechnical engineer based on site-specific soil conditions, PDA testing, and pile driving records. The structural capacity above is a preliminary estimate only.
