Impact of thermally induced soil deformation on the serviceability of energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria

This paper expands on the impact of the thermally induced deformation of the 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 perform ...

Performance-based Design of Energy Pile Foundations

Alessandro Francesco Rotta Loria

Over the past twenty years, an increasing amount of research has been performed to understand the multiphysical behaviour and to address the geotechnical and structural design of so-called energy piles, i.e. deep foundations that can serve any superstructu ...

Energy and geotechnical behaviour of energy piles for different design solutions

Lyesse Laloui, Alessandro Francesco Rotta Loria

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

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 ...

Geotechnical analysis of energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study proposes an analysis of the multiphysical phenomena and mechanisms governing the thermo-mechanical behaviour of energy piles. The analysis is based on the results of a series of full-scale in-situ tests, laboratory experiments and numerical anal ...

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 ...

Group action effects caused by various operating energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

To date, no field data referring to various operating energy piles over time-scales of practical applications had been made available to investigate the thermally induced “group action”. This paper presents the results of a full-scale field test and a thre ...
