Influence of model uncertainty and long term deformations in action effects calculation in reinforced concrete structures
Most codes of practice adopt a semi probabilistic design approach for the dimensioning and assessment of structures. Accordingly, structural safety is ensured by performing limit state verifications using design values determined with adequately calibrated ...
EPFL2024Short-term behavior of glass fiber-polymer composite bending-active elastica beam under service load application
Thomas Keller, Landolf-Giosef-Anastasios Rhode-Barbarigos, Tara Habibi
Bending-active elastica beam is a structural configuration that is based on the elastic deformation of an initially straight beam. This deformation occurs when horizontal displacements are applied to a sliding support, causing the beam to bend into an arch ...
2024Shear and steel-fibre reinforcement for the punching resistance of flat slabs at internal and edge columns
Reinforced concrete flat slabs consist of a continuous, thin concrete plate that rests on a grid of columns. The supporting surface of the columns is very small compared to the floor plan dimensions, leading to concentrations of shear forces near the colum ...
EPFL2024A novel fatigue life prediction methodology based on energy dissipation in viscoelastic materials, synergistic effects of stress level, stress ratio, and temperature
Thomas Keller, Lulu Liu, Abdolvahid Movahedirad
This work introduces a new methodology to predict the fatigue life of viscoelastic materials by considering the creep effect on fatigue behavior under the concurrent effects of stress level, stress ratio, and temperature. The model established based on the ...
2024Two-dimensional quasi-static delamination in composite laminates under Mode-I and Mode-II conditions
Fiber-polymer composites consist of a polymer matrix and reinforcing fibers made of various materials. These composites exhibit exceptional properties, such as a high strength-to-weight ratio and excellent corrosion resistance, which has led to their incre ...
EPFL2024Experimental and analytical investigation of shear-reinforced concrete and dowel action
Codes of practice can be overly conservative, particularly for the shear resistance of reinforced concrete beams with shear reinforcement when large loads act close to supports. This thesis addresses the topic by proposing a refined design approach based o ...

This data package supports the publication 'Complexity of crack front geometry enhances toughness of brittle solids' by Xinyue Wei, Chenzhuo Li, Cían McCarthy, and John M. Kolinski Nature physics (2024) - https://doi.org/10.1038/s41567-024-02435-x DOI: 1 ...
Zenodo2024Numerical investigation of two-dimensional Mode-II delamination in composite laminates
Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang
Delamination in real composite structures, which generally tends to grow in two-dimensions, sometimes cannot be appropriately represented by the widely accepted test methods where one-dimensional (1D) beam specimens are typically employed. In order to comp ...
2024Influence of fiber orientation on the tensile behavior of UHPFRC and reinforced UHPFRC under static and fatigue loadings
Ultra-high performance fiber reinforced cementitious composite (UHPFRC) is a modern class of cementitious building materials. Because of its superior mechanical properties and durability, it is increasingly used globally to rehabilitate, strengthen and mod ...
EPFL2024FLO:RE – A new floor system made of reused reinforced concrete and steel elements
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Numa Joy Bertola
Carefully extracting reinforced concrete (RC) elements from soon-to-be demolished structures and reusing them as load-bearing components is an emerging circular low-carbon alternative to building new structures. As floor construction typically accounts for ...
