Advances in the Soil-Structure Interaction Analysis -- from Surface Footings to Thermoactive Deep Foundations

Mutual interactions between soil and foundation play a fundamental role in the overall behaviour of constructions. Therefore, it is not surprising that soil-structure interaction has been the subject of numerous research works. This doctoral thesis is a th ...

Soil-structure interaction of surface footings

Lyesse Laloui, Cristiano Garbellini

Limit-state analysis of soil-structure interacting systems is a classical problem in theoretical and applied soil mechanics. Usually, the capacities of both components are evaluated separately. However, it is well known that soil-structure interaction play ...

Thermal stress analysis of energy piles

Lyesse Laloui, Cristiano Garbellini

This study is concerned with the problem of energy piles subjected to constant axial load and temperature variation uniform over the cross-section. In the first part of this article, equations for the analysis of energy piles based on elastic theory and th ...

Performance of Energy Piles Considering Reinforced Concrete Non-Linearity

Lyesse Laloui, Cristiano Garbellini

This study investigates the effect of reinforced concrete cracking on the performance of thermo-active piles subjected to traction force. A newly developed finite element code that is within the framework of the load-transfer approach is employed to simula ...

The role of thermal loads in the performance-based design of energy piles

Lyesse Laloui, Aurelio Muttoni, Cristiano Garbellini, Alessandro Francesco Rotta Loria, Matteo Bocco

Over the past two decades, a substantial amount of research has investigated the effects of thermal loads associated with the geothermal operation of energy piles on their mechanical response. Based on this research, consensus about the need for considerin ...

On the Soil-Structure Interaction of Surface Strip Footings at Ultimate Limit State

Lyesse Laloui, Cristiano Garbellini

Theoretical methods for estimating the bearing capacity of surface strip footings usually do not consider soil-structure interaction. A few publications deal with the subject, but all of these either do not apply rigorous methods or do not consider the gen ...
