Research Progress on Fire Resistance of Domestic and Overseas Wood Structure Buildings

In order to promote the development of modern wood structure buildings in China, this paper analyzed the key of wooden structure fire resistance and mainly introduced fire simulation test, building and structure fire resistance test, fire prevention materials application and insulation detection of cork product and the research progress of refractory application and achievements in the field of domestic and overseas refractory research of wood construction in the recent 20 years.On the basis of study and reference, the author put forward some existing problems and weak links in domestic research on wood structure buildings fire resistance compared with foreign research by summarizing foreign research results and experience.It is suggested to strengthen the theoretical foundation of domestic fire prevention research on wood structure buildings, especially the simulation test research, on the basis of the existing domestic and foreign standards and regulations on wood structure buildings to lay a foundation for the fire resistance evaluation of wood structure buildings.At the same time, it emphasized characteristic of cork material and put forward to use cork material cladding in place of components of wooden structure and its joining node.On the basis of ensuring practicability, it also played a role of insulation, heat insulation and decoration to further improve the refractory performance of wood components to improve the fire resistance of the building as a whole.Through the above analysis, to provide useful reference for the fire prevention optimization design and process testing of wood structure buildings in China.
