A Softening Constitutive Law and Gradient-Inelastic Fiber-Based Element for 3-Dimensional Frame Simulations Under Seismic Excitations
Steel frame structures are essential components of modern infrastructure. Understanding their behavior under seismic loading is critical for ensuring public safety and minimizing damage that occurs during earthquakes. To accurately predict the response of ...
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 ...
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 ...
IABSE2024Experimental 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 ...
EPFL2024Model uncertainties in action effects and load bearing capacity calculation in statically indeterminate reinforced concrete structures
Aurelio Muttoni, Alain Nussbaumer, Xhemsi Malja
For the dimensioning and assessment of structures, it is common practice to compare action effects with sectional resistances. Extensive studies have been performed to quantify the model uncertainty on the resistance side. However, for statically indetermi ...
Ernst & Sohn2024Micro 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 ...
Springer2024Experimental investigation of dowel action in reinforcing bars using refined measurements
Aurelio Muttoni, Marko Pejatovic
In typical reinforced concrete design, reinforcement is designed to carry axial forces, but it can also resist transversal forces by dowel action. This is usually neglected for simplicity's sake in the design phase, but it can be accounted for either expli ...
Ernst & Sohn2024Decarbonization 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 Ltd2024Exploring the potential of the critical shear crack theory for reinforced and post-tensioned glass beams: Initial analysis and experiments
Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac
In the evolution of structural glass beam elements, the requirements for post-fracture load bearing capacity and safe failure behaviour have led to the development of reinforced and post-tensioned beams. Maximum bending capacity in the post-fracture state ...
2023Optimization of the environmental impact of beams
In the European Union, building construction accounts for 40% of materials consumption, 40% of overall energy consumption, and 40% of waste production [1]. It is therefore essential to reduce the environmental impact of these structures. Various levers are ...
