May 10, 2021When the strength of the supporting material is considerably less than the steel, the H-piles obtain support by the development of an increased bulb of pressure around the toe and friction along the embedded length. H-piles are generally most efficient when driven through relatively deep, soft to medium stiff clays to end bearing.

Fig. 2.2.1(a)—A simple beam loaded in the middle and supported at the ends will tend to deflect or bend down in the middle, causing tensile stress in the bottom of the beam and tending to pull it apart. That is, the bottom of the beam is in tension. Reinforcing steel near the bottom of the beam will resist this tension and hold it together.
