Description du projet
Une technologie du bois pour des immeubles de grande hauteur durables
Les éléments en bois massif à queue d’aronde (DMWBE, pour «dovetailed massive wood board elements») sont basés sur l’une des plus anciennes techniques traditionnelles utilisées en menuiserie. Bien que de nombreuses études aient été menées sur les aspects technologiques, écologiques, sociaux et économiques des produits en bois d’ingénierie (PBI) dans le secteur de la construction, aucune n’a évalué les performances techniques des DMWBE dans les bâtiments à plusieurs étages. Le projet DoMWoB, financé par l’UE, développera des DMWBE pour les bâtiments à plusieurs étages en remplacement des PBI conventionnels, grâce à une collaboration multidisciplinaire impliquant l’architecture, la structure et la physique du bâtiment. L’initiative concevra, construira, testera et mènera des études de marché sur les DMWBE et favorisera la compétitivité de la construction industrielle en bois finlandaise à grande échelle et ses opportunités e en matière d’économie circulaire, ainsi que le développement durable à l’appui de la politique climatique de la bioéconomie européenne.
Objectif
In engineered wood products (EWPs), adhesives play an essential role particularly by helping save wood, making the structure light and robust, and moderating the expansion and contraction due to the inherent moisture. Although there are many advantages associated with EWPs, the use of adhesives causes some concerns about their sustainability, recyclability, and broader environmental impact. In addition to these detrimental substances, metal connectors used in EWPs have a negative impact on their end-of-life disposal, reusability, and recyclability.
Thus, there is still room for a solution that is solid and completely pure wood enabling as healthy indoor air as possible (adhesive-&metal-connectors-free) dovetailed massive wood board elements (DMWBE) based on one of the oldest joining methods used traditionally.
In the literature, numerous studies have been conducted on the technological, ecological, social, and economic aspects of EWPs in the construction with different building solutions, however, no studies have made an attempt to evaluate the technical performance of DMWBE in multi-story or tall construction. Overall, the aim of this research is to promote the competitiveness of Finnish large-scale industrial wooden construction at the local level and to create higher value-added circular economy opportunities in support of European climate policy as part of the bio-economy and sustainable development.
To achieve this goal, DMWBE for multi-story buildings to the global market as a replacement of conventional EWPs e.g. cross-laminated timber, glue-laminated timber will be developed by enabling the confidence of its technical performance and suitability within the interdisciplinary collaborations among architecture, structure, and building physics. The following main objectives have been identified: Designing, building, and testing, and finally conducting market research of DMWBE in multi-story, maybe even tall, construction.
