A global framework for data-informed bridge examination
Eugen Brühwiler, Numa Joy Bertola, Philippe Schiltz
Examining the performance of an existing bridge requires information on several aspects, such as design choices, material properties, and ongoing degradation processes. It often happens that some critical information is not available. The traditional appro ...
2024Development of a scintillator based fast-ion loss detector for the Wendelstein 7-X stellarator
A new scintillator based fast -ion loss detector (FILD) system has been designed for the Wendelstein 7-X (W7X) stellarator. The mechanical design of the system is presented here along with engineering analyses of the system. This includes an assessment of ...
2024Experimental Investigation on Size-Effect of Rubble Stone Masonry Walls Under In-Plane Horizontal Loading: Overview and Preliminary Results
Katrin Beyer, Savvas Saloustros
Rubble stone masonry is a common construction typology of historical city centres and vernacular architecture. While past earthquakes have shown that it is one of the most vulnerable masonry construction typologies, there are few experimental campaigns giv ...
2024Influence 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 ...
EPFL2024Instabilities in Elastic and Magneto-Elastic Beams and Shells: from Shell Buckling to the Design of a Programmable Braille Reader
In this thesis, we conduct a comprehensive investigation into structural instabilities of both elastic and magneto-elastic beams and shells, resulting in a creative proposal to design a programmable braille reader. Methodologically, we combine numerical si ...
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 ...
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 ...
EPFL2024Mesh-based topology, shape and sizing optimization of ribbed plates
In this paper, we present a new parameterization and optimization procedure for minimizing the weight of ribbed plates. The primary goal is to reduce embodied CO2 in concrete floors as part of the effort to diminish the carbon footprint of the construction ...
Springer2024Design Progress of Structural Components of the EU DEMO EC Equatorial Launcher
Jean-Philippe Hogge, René Chavan
The EU DEMO Tokamak is foreseen to be equipped with an electron cyclotron (EC) system for plasma heating, magnetohydrodynamic (MHD) control, and thermal instability suppression. Up to six launchers will be installed into equatorial ports with the aim to in ...
Piscataway2024FLO: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 ...
