Summary
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.

Summary
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.

Summary
CLT-concrete composite floor systems are a solution for timber buildings with a long-span floor. It yields a reduction of carbon footprint and even eco-friendly structure at the end of its service life. This study will evaluate the structural performance of notched connectors in the CLT-concrete composite floor, comprised of the serviceability stiffness, maximum load, and behavior at failure. The parameters of the test plan are the loaded edge length, the notch depth, the concrete thickness, and the screw length. Other secondary variables are also assessed, such as different loading sequences, speed of test, and timber moisture content. Experimental results prove that the performance of the connector depends significantly but not linearly on the notch depth and the length of the loaded edge. The connector with a deeper notch and a shorter heel will be stiffer and more robust, but it also tends to have a brittle rupture. The test results also help validate a solution for deconstructable connector systems. A nonlinear finite element model of the connector is built and validated versus the experimental results. It yields reasonably good predictions in terms of resistance and can capture the load-slip relationship.
