Abstract The ancient wooden buildings have been preserved after years of wind and rain, as well as damaged to different degrees. Most of the ancient wooden buildings are important cultural resources of the country; they are precious cultural heritages, and not recoverable. Therefore, it is particularly important to protect these ancient buildings. This paper analyzes and discusses the destruction form, repair principle and reinforcement method of ancient wooden buildings, and puts forward the shortcomings of existing technology, hoping to provide reference for effective protection of ancient wooden buildings in the future.

preserved in China. There were 4295 national key cultural relics protection objects in 2013 according to statistics, including 1882 ancient cultural building relics, which accounts for 43.82%, nearly half of total national key cultural relics protection objects (Li et al. 2017). Most ancient wooden buildings are important national tourism culture resources of the country, which are precious cultural heritages and not recoverable. Repair and reinforcement of ancient wooden buildings are of great significance, because ancient buildings have been damaged due to years of earthquake, lightning stroke, and other natural disasters; moreover, wooden materials are easy to be cracked and deformed.
2 Destruction Form of Ancient Wooden Buildings 1 Introduction Chinese ancient buildings which have formed a unique architectural style in the world jointly constitute three largest architecture system in the world with European buildings and Islamic buildings. Lots of ancient building relics with wooden structures have been
As ancient wooden buildings have been subject to years of wind and rain and long-term load, their wood properties are degraded with destruction in different forms. Destruction form mainly includes member cracking, material decay, deformation of flexural members, and joint skipping. 2.1 Member Cracking

disasters, their wood properties will be degraded, leading to cracking, which is the most common destruction form of wood members. Cracking of wood members will lead to degradation of ultimate bearing capacity and mechanical support property, which will influence security of integral structures of ancient buildings and will lead to water inflow of wood members so as to lead to decay
