A comprehensive review on geomembrane systems application in hydropower
Giovanni De Cesare, Samuel Luke Vorlet
Geomembrane systems have been used at hydropower plants as rehabilitation and mitigation technology for several decades and are now used worldwide. In the context of planning an energy transition that promotes the sustainable use of water resources for ene ...
2024Development of a numerical model to assess the influence of fluid-structure interactions on the dynamic behavior of geomembrane systems in pressure waterways
The need to maintain and expand hydraulic structures is a major challenge for the coming energy transition, especially in Western countries. One technique already widespread allowing to meet these issues consists in the use of geomembranes to overcome prob ...
2023Dynamic behavior of exposed geomembrane systems in pressure waterways
Giovanni De Cesare, Samuel Luke Vorlet, Roberto Proença Seixas
Geomembrane systems have been used in dams and reservoirs as rehabilitation technology since several decades and are now used worldwide. They act as impervious layer to prevent and mitigate water leakage and damage to structures. They meet the needs of man ...
CRC Press/Balkema2023Studies on the mechanical evolution of compacted bentonite subjected to environmental actions
Deep geological disposal is currently the most feasible option for the long-term isolation of radioactive waste, consisting in emplacing the waste into tunnels or drifts excavated at great depths in suitable geological formations. The use of bentonite, a h ...
EPFL2021Out-of-plane permeability measurement for reinforcement textiles: A benchmark exercise
Véronique Michaud, Damiano Salvatori, Baris Çaglar, Amaël Maximilien Cohades
The out-of-plane permeability of two glass fibre fabrics was measured by 26 institutions using silicone oil as a test fluid. Participants in this study were free to select the test procedure, specimen dimensions and data analysis method, provided that test ...
2021A 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)2021Combined Shear-Flexural Verification Of In Plane Loaded Reinforced And Unreinforced Masonry Walls
The safety verification of in-plane loaded masonry panels requires the evaluation of at least three different collapse conditions connected with overturning, shear sliding, and shear - compression failure at the panels' toe. In reinforced panels, the resis ...
INT CENTER NUMERICAL METHODS ENGINEERING2021A numerical study on the coupled hydro-mechanical behaviour of compacted bentonite
Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu
Understanding the mechanical behaviour of compacted bentonite upon re-saturation is of outmost importance in most designs of nuclear waste disposal repositories. The behaviour of bentonite is characterized by its stress-path dependency and it is typically ...
