DOVETAILED MASSIVE WOOD BOARD ELEMENTS FOR MULTI-STORY BUILDINGS

Project description

Wood technology for sustainable high-rise buildings

Dovetailed massive wood board elements (DMWBEs) are based on one of the oldest traditional techniques used in joinery. Although numerous studies have been conducted on the technological, ecological, social and economic aspects of engineered wood products (EWPs) in the construction sector, none has evaluated the technical performance of DMWBEs in multi-story buildings. The EU-funded DoMWoB project will develop DMWBEs for multi-story buildings as a replacement of conventional EWPs through a multidisciplinary collaboration, involving architecture, structure, and building physics. The initiative will design, build, test and conduct market research on DMWBEs and promote the competitiveness of Finnish large-scale industrial wooden construction and circular economy opportunities, as well as sustainable development in support of Europe's bio-economy climate policy.

Objective

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.
