Abstract: During winter, energy piles are subjected to cooling cycles due to the cyclic operation of the ground source heat pump (GSHP). The cyclic operation of the heat pump causes the energy pile to contract and expand axially and ...

Abstract: Granular column ground-improvement methods are widely used to improve bearing capacity and provide a drainage path. However, the behavior of granular columns depends on the confinement provided by the surrounding soil, ...

Abstract: A constitutive model was developed for high density polyethylene (HDPE) pipe material using published data considering the strain rate effect. A hyperbolic model was used and a conventional approach was employed to estimate ...

Abstract: Granular column ground-improvement methods are widely used to improve bearing capacity and provide a drainage path. However, the behavior of granular columns depends on the confinement provided by the surrounding soil, ...

Abstract: Predicting the load–settlement and load–transfer behaviors of rammed aggregate piers are important aspects of design. Use of advanced engineering models, however, can be complex involving uncertainty in selection of nonlinear ...

Abstract: In the United States, an estimated $1 billion is spent annually on repair and replacement of deep foundations. In a recent study, the possibility of using ultrahigh-performance concrete (UHPC) for deep foundation applications ...

Abstract: A fully instrumented experiment was conducted to investigate the soil-structure interaction of single short, stiff laterally loaded piles. A hollow steel pipe pile with a diameter of 102 mm, a thickness of 6.4 mm, and a ...
