Energy geotechnology: A new era for geotechnical engineering practice

Lyesse Laloui, Melis Sütman

Energy geotechnology provides low carbon, cost-effective and local energy solu-tions to structures and infrastructures, which opens a new era for the geotechnical engineering practice, by extending the conventional role of structural design to the ...

Microstructure observations in compacted clays subjected to thermal loading

Lyesse Laloui, Melis Sütman, Roba Houhou

The response of clayey materials to thermal variation has been the subject of extensive studies, given the wide range of engineering applications which involve subjecting soils to substantial temperature fluctuations. A number of hypotheses have been propo ...

Thermally induced group effects characterise closely spaced energy piles. It has been observed experimentally that the behaviour of energy piles subjected to mechanical and thermal loads, in which the piles are located sufficiently close to each other, is ...

Cyclic thermomechanical response of fine-grained soil-concrete interface for energy piles applications

Lyesse Laloui, Elena Ravera, Melis Sütman

Understanding the behaviour of soil-structure interfaces is critical for addressing the analysis and design of energy geostructures. In this study, the interface failure mechanism of energy piles (where a shear band is detached from the surrounding soil th ...

The behavior of an energy pile in a group is different from that of an isolated energy pile due to thermal and mechanical interactions. This study aims to extend the load transfer method to consider the mechanical and thermal interactions of energy piles i ...

Analysis of the interaction factor method for energy pile groups with slab

Lyesse Laloui, Elena Ravera, Melis Sütman

The design of energy pile is hampered by the complex interaction between the piles and the slab subjected to thermal loads. Although finite element analysis is used to account explicitly for the interactions, this method is mainly considered as a research ...

Full-scale in-situ tests on energy piles: Head and base-restraining effects on the structural behaviour of three energy piles

Melis Sütman

Energy piles, due to their dual roles, are exposed to temperature change throughout their life time, which may cause axial displacements, additional axial stresses and changes in the shaft resistance along their lengths. The extent of these effects highly ...

Cyclic Load-Transfer Approach for the Analysis of Energy Piles

Lyesse Laloui, Melis Sütman

Moreover, a two-dimensional finite-element model has been developed by incorporating unloading-reloading responses into the monotonic load-transfer curves to define the soil-energy pile interaction during heat exchange operations. In this paper, the develo ...

Long-term performance and life cycle assessment of energy piles in three different climatic conditions

Lyesse Laloui, Alessio Ferrari, Melis Sütman, Gianluca Speranza

The main purpose behind the use of energy piles is to enable the exploitation of geothermal energy for meeting the heating/cooling demands of buildings in an efficient and environment-friendly manner. However, the long-term performance of energy piles in d ...

Energy geostructures: anew era for geotechnical engineering practice.

Lyesse Laloui, Melis Sütman

Energy geostructuresprovide low carbon, cost-effective and local energy solutions to structures and infrastructures, which opens a new era for the geotechnical engineering practice, by extending the conventional role of geotechnicaldesign to the one of add ...
