Structural component reuse of precast and cast-in-place reinforced concrete in architecture since the late 1960s in Europe
Corentin Jean Dominique Fivet, Célia Marine Küpfer
The reuse of concrete pieces salvaged from structures undergoing transformation or demolition into new architectural projects has gained a sudden and visible interest over the past five years. However, the practice of reusing concrete pieces in new structu ...
vdf Hochschulverlag AG2024Reusability assessment of reinforced concrete components prior to deconstruction from obsolete buildings
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Julie Rachel Devènes
A large part of building demolitions is motivated by purely socio-economic reasons. Hence, about-to-be-demolished structures, commonly made of reinforced concrete, very often present no or little degradation. When adaptive reuse of the entire building is n ...
2024Contributions to rebar-to-concrete interaction and its structural implications for design and monitoring applications
Bond between reinforcing bars and concrete has been the focus of extensive research over the last century. This is well-justified as the functioning of reinforced concrete intimately depends on the interaction between rebar and concrete, as for example cra ...
EPFL2024A concrete answer for circular construction: three prototypes reusing saw-cut elements
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer
Existing concrete buildings should be retained for as long as possible to reduce the environmental burden of demolition and new construction. However, when urban pressure makes demolition unavoidable, salvaging and reusing concrete elements elsewhere in ne ...
2024Experimental 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 ...
EPFL2024Estimation of the bar stress based on crack width measurements in reinforced concrete structures
Estimating the stress of reinforcing bars and its variations in service conditions can be useful to determine the reserve capacity of structures or to assess the risk of fatigue in the reinforcement. This paper investigates the use crack width measurements ...
Ernst & Sohn2024Experimental 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 & Sohn2024FLO:RE – A new floor system made of reused reinforced concrete and steel elements
Corentin Jean Dominique Fivet, Numa Joy Bertola, Maléna Bastien Masse, Célia Marine Küpfer
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 ...
IABSE2024Mesh-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 ...
Springer2024Influence 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 ...
