HP12×84 H-pile

Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.

HP12×84 measures 12 1/4 in. deep with a 12 1/4 in. flange, on a 11/16 in. web and 11/16 in. flanges.

At 84 lb per foot it is one of the 5 HP12 sizes, which run from 53 to 89 lb/ft.

For strong-axis bending its section modulus is Sx = 106 in³ and its moment of inertia Ix = 650 in⁴, with a plastic modulus Zx = 120 in³.
