With the arrival of innovative fasteners (e.g. self-tapping screws), assembly principles have greatly changed and now resemble a metal framework. Although a significant amount of information is available in the literature, it often indicates short-term flammability resistance (± 30 min), which is largely insufficient for buildings that need to provide a fire resistance rating of at least 2 hours. The objective is to carry out a literature review to understand the factors influencing the fire performance of assemblies in wood construction. A modeling of thermomechanical behavior and a simplified analytical approach should be developed. Testing from an intermediate furnace is likely to be required to validate model assumptions.
