Eiffage Construction signs an R&D partnership with the Centre Scientifique et Technique du Bâtiment (CSTB) and PiveteauBois

April 12th, Eiffage Construction, the CSTB and PiveteauBois signed, during the Forum Construction Bois in Dijon, a research and development partnership on the analysis and multi-criteria design of wood flooring systems.

The development of wood construction projects calls for the resolution of various technological issues and dimensioning optimization. This supposes multicriteria analyzes integrating the acoustic and vibratory phenomena and taking into account the environmental weight of the choices made.

This is for example the case for wood floors, for which certain technical requirements have a significant impact, particularly in terms of thickness and surcout associated. This raises a central question: is it possible to design and dimension given wood floor systems, while minimizing their thickness and ensuring compliance with the requirements for acoustic, dynamic and thermal comfort, as well as the requirements for structural resistance?

The committed R&D partnership is based on a twofold approach:

  • a multicriterion analysis integrating the acoustic and vibratory phenomena and taking into account the environmental weight of the choice of processes;
  • design assistance through numerical modeling and testing.

The work will be multi-scale, from the material to the work integrating the systems. They will be focused on a set of three types of wood flooring systems developed by Eiffage Construction, CSTB and PiveteauBois.

The work carried out aims to bring out innovative technical solutions to optimize the performance of wood floors, in compliance with the requirements of acoustic, dynamic and thermal comfort in the two distinct areas of employment: housing and the tertiary sector.

This research program will take place over a period of 12 to 15 months. The results will be shared during 2019.
