The role of thermally induced soil deformation on the serviceability of energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

This paper investigates the impact of the thermally induced deformation of soil on the serviceability mechanical performance (i.e., deformation-related) of energy pile groups. The work is based on the results of a full-scale in-situ test that was performed ...

The interaction factor method for energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria

Prior to this study, no simplified yet rational methods were available for estimating the vertical displacements of energy pile groups subjected to thermal loads. Observing such a challenge, the goal of this study has been threefold: (i) to extend the inte ...

Numerical modelling of energy piles in saturated sand subjected to thermo-mechanical loads

Lyesse Laloui, Alessandro Francesco Rotta Loria, Chao Shi

This study investigates the impact that different magnitudes and combinations of thermal and axial mechanical loads have on the mechanical behaviour of energy piles in saturated sand. The work is based on the results of a series of thermo-hydro-mechanical ...

Numerical study on the suitability of centrifuge testing for capturing the thermal-induced mechanical behavior of energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria, Alice Di Donna

Currently, the suitability of centrifuge testing for capturing the thermal-induced mechanical behavior of full-scale energy piles has not been established, yet, despite their increasing worldwide development. Looking at this challenge, this paper investiga ...

Energy and geotechnical behaviour of energy piles for different design solutions

Lyesse Laloui, Alessandro Francesco Rotta Loria, Niccolò Batini

Energy piles are heat capacity systems that have been increasingly exploited to provide both supplies of energy and structural support to civil structures. The energy and geotechnical behaviours of such foundations, which are governed by their response to ...

Predicting the axial capacity of piles in sand

Lyesse Laloui, Jean-Marie Fuerbringer, Alessandro Francesco Rotta Loria, Alberto Minardi, Luis Felipe Orellana Espinoza

Currently, although several tools have been proposed for the numerical modelling of the pile-soil interface, there is not a well-established framework concerning the quantitative impact that different estimations of the mechanical properties of this settin ...
