Drained Clay-Pipe Interface Resistance at Low Normal Stresses and Elevated Temperatures
Offshore pipelines that transport hydrocarbons under high pressure and high temperature are usually thermally insulated to maintain an elevated temperature and prevent any heat loss to the surroundings. However, the temperatures at the outer-wall of the pi ...
AMER SOC CIVIL ENGINEERS2023Drained Axial Pipe-Soil Resistance at Low Confinement Using Tilt Table and Direct Shear Tests
Establishing a reliable value for the axial pipe-soil interface resistance is critical for the design of offshore pipelines. Over the last few years, several independent research groups have modified existing methodologies or devised new testing setups to ...
ASCE-AMER SOC CIVIL ENGINEERS2022Failure mechanism of fine-grained soil-structure interface for energy piles
The response of the soil-structure interface can significantly affect the performance of any geotechnical structure. Thermal cycles are a new factor that influence the response to all structures that have an energy function in addition to the structural on ...
2022A mechanical approach for the maximum punching resistance of shear-reinforced slab-column connections
Aurelio Muttoni, Miguel Fernández Ruiz, João Tiago Ramos Bernardo de Santa Rita Simões, Diego Hernández Fraile
The use of punching shear reinforcement is currently considered as one of the most convenient practices to enhance the punching shear strength and deformation capacity of slab-column connections in flat slabs. Intensive research has been performed in the l ...
Fédération Internationale du Béton (fib)2021Cyclic 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 ...
2020Geotechnical and environmental performance of retaining structures in unsaturated soils
Presently, environmental issues are considered as critical aspects concerning the market competitiveness in the building and construction sector. However, the construction sector is regarded as one of the main areas contributing to CO2 emissions and resour ...
EPFL2020Impact of Mineralogical Composition on Geotechnical Properties of Opalinus Clay
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci
Opalinus Clay is the selected host geomaterial for the construction of underground geological disposals for radioactive waste in Switzerland. The formation has been studied in several sites, i.e. the Mont Terri laboratory, and several boreholes in the nort ...
2019Abaqus models and input files for simplified micro models of in-plane loaded masonry walls
Katrin Beyer, Bastian Valentin Wilding, Kiarash Mohtasham Dolatshahi
The data set contains the Abaqus input files of the numerical analyses presented in two research papers. 1) Influence of load history on the force-displacement response of in-plane loaded unreinforced masonry walls, Engineering Structures, 2017, L ...
Zenodo2019Numerical investigation of the role of masonry typology on shear strength
The force-displacement behavior of masonry elements depends on the properties of their constituents, mortar and unit, as well as on their typology, i.e., the shape and size of the units and the patterns they generate. Up until now, only few numerical studi ...
ELSEVIER SCI LTD2019One Dimensional Consolidation of Opalinus Clay from Shallow Depth
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci
First experimental results on Opalinus Clay from shallow depth (< 30 m depth) are presented and compared to results on cores from Mont Terri Underground Rock Laboratory (~ 300 m depth). Samples were tested in one dimensional condition using an advanced exp ...
