Insights from an extensive triaxial testing campaign on a shale for comparative site characterization of a deep geological repository
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci
Several boreholes were drilled for site comparison of a deep geological repository (DGR) in Northern Switzerland. The main target of the exploration program was the >100m thick Opalinus Clay, the designated host rock encountered at approximately 450 to 100 ...
Amsterdam2024Micro modeling of irregular stone masonry walls using mathematical programming
Katrin Beyer, Qianqing Wang, Ketson Roberto Maximiano Dos Santos
While understanding the shear strength of stone masonry structures is important for the design and the mainte- nance, we still lack computational tools for predicting the strength as a function of the stone layout. Here we implement an end-to-end image bas ...
Springer2024Numerical Modeling of FRP-Strengthened Masonry Structures Using Equivalent Frame Models
Katrin Beyer, Francesco Vanin, Ivana Bozulic
The present study focuses on enhancing the seismic resistance of existing masonry structures. To that aim, the use of fiber-reinforced polymer (FRP) strengthening serves to improve structural behaviour by attaching FRP strips to the masonry walls. Despite ...
Springer2024Decarbonization potential of steel fibre-reinforced limestone calcined clay cement concrete one-way slabs
This study deals with a comparison of the environmental performance of one-way slabs utilizing steel fibrereinforced limestone calcined clay cement (LC3) concrete with the control case of Ordinary Portland cement concrete. The experimental program constitu ...
Elsevier Sci Ltd2024Hydro-mechanichal characterisation of bentonite/steel interfaces
Alessio Ferrari, Eleni Stavropoulou, Fabiana Sannasardo
The hydromechanical response of a Wyoming-type bentonite (MX-80) and its interface with steel was studied in terms of shear resistance under different hydration levels. A series of shear tests under constant normal stress were performed in total suction co ...
2023Shear strength and shear stiffness analysis of compacted Wyoming-type bentonite
Wyoming-type bentonite is one of the materials to be used as part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.In the KBS-3 type repository, the canisters containing the spent fue ...
ELSEVIER2023Drained 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 ENGINEERS2023On the Post-peak Behaviour of Remoulded and Jointed Clay Samples During Triaxial Compression Tests
The note presents a selection of the results of a large experimental program conducted with the aim of characterizing the shear strength of Opalinus Clay and Speswhite Kaolin in remoulded and reconstituted conditions, through the execution of unconventiona ...
2023Incorporation of Lignin in Bio-Based Resins for Potential Application in Fiber-Polymer Composites
Mário Alexandre De Jesus Garrido, Mateus De Assunção Hofmann
Bio-based resins, obtained from renewable raw materials, are a more sustainable alternative to oil-based resins for fiber-reinforced polymer (FRP) composites. The incorporation of lignin in those resins has the potential to enhance their performance. This ...
MDPI2023Pore-pressure coefficients for unsaturated soils: generalized effective stress approach
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Geotechnical problems with total stress changes occurring rapidly relative to the soil consolidation time can be conveniently addressed using an effective stress-based approach. For saturated states, analytical formulations of pore-pressure coefficients ad ...
