Today, more and more wooden cabins are being built in Norway. Most of these cabins are built in mountainous areas. One of the main challenges of mountain cabins is the avalanche hazard that causes major or minor accidents such as loss of life and values. Therefore, the stability of the mountain cabins is important in relation to such natural phenomena. The characteristics of the cabin’s components are crucial to how they behave, and a greater understanding of how different parameters affect the cabin’s stability is important for the development of the cabins. This thesis is divided into two parts; a technical part that studied the analysis of Norwegian wooden cabins against avalanches and an economic part that has looked at the role of wood in circular economy. In the technical part, this thesis focuses on horizontal stability of wooden cabins according to the Norwegian standard. The cabin was designed in the TimberTech software where the wind load was used as a horizontal load instead of avalanche load. Two different cases were investigated to reveal how change of the building’s components and their properties affect the cabin’s stiffening. Analyses showed that stiffness and mass are important parameters for horizontal stiffening. Furthermore, hold down anchors are important components for sliding protection, tension and to prevent uplifting of walls. Location of shear walls is also important for increased horizontal stiffening so that the structure can take shear forces, prevent rotations and distribute the horizontal forces in all directions. The economic part of the thesis has looked at the role of wood in circular economy. Properties of wood materials were discussed and compared to other buildings materials. Wood is a natural and renewable material that can contribute to emissions reduction. The construction industry is included as a large consumer of resources and greenhouse gas emissions and wood as building materials can be important materials for transition to circular economy.
