Serviceability assessment of energy pile groups through design charts

Lyesse Laloui, Alessandro Francesco Rotta Loria

The estimation of the vertical displacement of energy pile groups subjected to thermal (and mechanical) loads is needed for a complete geotechnical and structural design of the piles in situations where these foundations may be located sufficiently close t ...

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 ...

Thermally induced group effects among energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

The behaviour of conventional pile groups (e.g., closely spaced) that are subjected to mechanical loads has been shown to be different than the behaviour of single isolated piles. The so-called group effects are responsible for this behaviour and must be c ...

Recent development in the multiphysical analysis and design of energy piles

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study proposes an analysis of the multiphysical phenomena 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 analyses. First, th ...

The equivalent pier method for energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study presents a method for estimating the average vertical displacement of energy pile groups subjected to thermal loads. The method consists of replacing any regular energy pile group with a single equivalent pier of the same length and an equivalen ...

Displacement interaction among energy piles bearing on stiff soil strata

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study presents an analysis of the displacement interaction among general configurations of energy piles bearing on stiff soil strata that are subjected to thermal loads. This work integrates recent analyses investigating the displacement interaction a ...

Multiphysical phenomena and mechanisms involved with 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 ...

Analysis of thermally induced mechanical interactions in energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study investigates the thermally induced mechanical interactions among closely spaced energy piles that partially operate as geothermal heat exchangers over a time-scale that is typical of practical applications. The analysis is based on the results o ...

Numerical study of the response of a group of energy piles under different combinations of thermo-mechanical loads

Lyesse Laloui, Alessandro Francesco Rotta Loria, Alice Di Donna

Energy piles are rapidly gaining acceptance around the world because they represent a renewable and clean source of energy that can be used for the heating and cooling of buildings, and the de-icing of infrastructures. This technology couples the structura ...
