“…Step 1 —Different dosages of fibers from 40 to 78 kg/m 3 , different sectional percentages of bottom rebars from 0 to 8.8%, and different thicknesses of the upper track layer (B3) from 15 to 24 cm were considered in the numerical simulations. Rebars, with a length of 40 cm, were used as in the first study [ 27 ]. As requested by the industrial team, only the technical solutions leading to crack openings less than or equal to 100 µm were retained at this step.…”

This paper focuses on the use of numerical tools, as a finite elements method, to conceive fiber reinforced concrete (FRC) eco-constructions. It highlights the fact that these are the most suitable tools (much more than the Eurocodes, for example) to predict the cracking process of FRC constructions at their service limit state and, therefore, to predict their durability. Following a critical analysis of the existing finite element models for FRC cracking, it describes in more detail a probabilistic one. This model appears very suitable for providing precise information about crack openings that are inferior or equal to 300 microns. Finally, it presents an example of the use of this numerical model to optimize an FRC track slab in order to reduce its carbon footprint. This study, although partial and incomplete, shows that the best way to reduce the carbon footprint of this type of construction is to reduce its thickness.
