Abstract Ground Source Heat Pumps (GSHPs) have been installed all around the world to
harvest shallow geothermal energy for heating and cooling building envelopes. However …

Heat transfer from/to energy piles can cause plastic contraction of soft clay with a low
overconsolidation ratio (OCR) during heating and cooling. This can lead to thermally …

There is an increasing interest and use of energy foundation worldwide. Full-scale tests,
physical model tests at one Earth's gravity and at elevated gravity in a geotechnical …

Thermally induced ratcheting of a thermo-active pile is the accumulation of net and
irreversible pile head displacement upon heating–cooling cycles. Although this kind of …

Thermal elongation of energy piles (EPs) depends on the end restraints to displacement.
The EP head is restrained by a working load and non-energy piles (NEPs) within an energy …

This paper describes a test setup and methodology for centrifuge modeling of energy pile
pullout from saturated soft clay, with the goal of understanding how pile heating improves …

This paper presents the results of a series of cyclic nonsymmetrical thermally loaded model-
scale tests conducted on floating pile groups, with and without a rigid cap in saturated clay …

This study presents the results from centrifuge modeling experiments performed to
understand the effects of temperature changes on the vertical pullout capacity of scale …

During heating or cooling, an energy pile elongates or shortens around the null point, where
the thermally induced displacement is zero. Previously proposed computing methods …

This paper examines the shaft resistance mobilisation ratio as a predictor of cumulative
displacement of small-scale floating and end-bearing energy pile foundations subjected to …
