This paper presents a design method for multi-story timber building with consideration of regulatory constraints. The objective is to optimize in the same time thermal, structural and environmental objectives taking into account the industrial feasibility. To set up this method and the appropriate tool a study case is developed and will be implemented.
This paper presents a multifunction timber wall concept. It is adapted to create frame and envelope of multi-storey buildings. This wall is composed of a reinforced CLT thin panel to support the loads. Other layers are used to provide insulation, internal and external coatings. In this study, Solid-beams are chosen to reinforce the CLT panel. Bending and buckling tests are carried out to assess the mechanical behavior of the wall concept. The implementation of reinforcements increases significantly the stiffness of CLT thin panel and its buckling stability. In this way, the use of this wall reduces the amount of material employed. This study also shows that it is possible to reduce the length of the reinforcements without significantly reducing the buckling stability of the wall.
