FLO: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 ...

Case-Study on the Creep Behavior of Interconnected Timber Elements using Wood-Wood Connections

Yves Weinand, Julien Gamerro, Martin Thomas Nakad, Jean-François Bocquet

With the increasing use of automation and computer-aided manufacturing in timber construction, a standardized timber construction system using digitally produced wood-wood connections has recently been developed for basic building components. Its structura ...

Structural design methodology in Integrally-Attached Timber Plate structures

Petras Vestartas, Aryan Rezaei Rad

The immediate application of research discoveries requires a global and exact understanding of the structure under consideration. To gain insight into the complex behavior of structures, numerical simulations are carried out in parallel to physical experim ...

Development of Novel Standardized Structural Timber Elements Using Wood-Wood Connections

Julien Gamerro

Traditional wood-wood connections, widely used in the past, have been progressively replaced by steel fasteners and bonding processes in modern timber constructions. However, the emergence of digital fabrication and innovative engineered timber products ha ...

Monitoring of the UHPFRC strengthened Chillon viaduct under environmental and operational variability

Constructed in 1969, the Chillon viaducts constitute a vital component of the Swiss roadway network. The bridge deck was strengthened in 2015 by means of an Ultra High Performance Fiber Reinforced Cement-based Composite for alleviating the effects of deter ...

Design of Truss Structures Through Reuse

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting, Joseph Jean François Desruelle

This paper presents structural optimization techniques to design truss structures that make best use of a given stock of structural components. Still little explored, the reuse of structural components over multiple service lives has the potential to signi ...

Segmented Spiral Using Inter-Connected Timber Elements

Yves Weinand, Petras Vestartas, Aryan Rezaei Rad, Martin Thomas Nakad, Loïc Henri Pelletier

This paper describes the construction process of a scenographic structure five meters high spiral. It consists of following parts: CAD modeling workflow, prototyping and FEM structural calculation, assembly and on-site loading test. The structure was compo ...
