The Research And Analysis Of The CFRP Strengthening Method Of Huizhou Traditional Building Beams

Ancient architecture is the carrier of the world's cognitive history,but also an important historical and cultural heritage.Huizhou wooden ancient buildings is the sediment of the ancient Huizhou region culture,with bright achievements,strong local characteristics and rich artistic value and historical value.However,during the long historical years,the majority of Huizhou traditional wooden buildings were damaged due to the destruction of natural forces and human factors.The reinforcement and restoration of the ancient buildings wooden structure is imminent.The traditional reinforcement methods often cause problems of chemical corrosion and rust on the ancient buildings with wooden structures.Therefore,the CFRP materials with light weight,corrosion resistance and convenient construction are used to repair and reinforce the Huizhou traditional architectural wood.The research of structure method is urgent.The main contents and results are as follows:(1)By referring to a large amount of documents and materials,this paper elaborates the current situation of Huizhou traditional architecture and the reasons for the current situation.It also analyzes the significance and purpose of the study of Huizhou traditional architecture repair and reinforcement.(2)Based on literature research and field research,a detailed analysis of the reasons for the damage of Huizhou traditional building timber,then summarizes the ancient timber frame beam reinforcement repair method is introduced,method of reinforcement replacement repair beams tenon.(3)Summed up the limit of CFRP reinforcement beams bearing capacity formula to replace the tenon,verify the CFRP reinforced beams of the feasibility of replacing the tenon.(4)Using a traditional residence in Huizhou as an example,select one damaged,need to replace the tenon reinforcement beams as the research object,by calculating the actual load bearing beams.(5)To replace the traditional architecture in Huizhou CFRP beams with different reinforcement methods are tenon numerical analysis by using finite element software.The research shows that carbon fiber cloth has better effect on constraint interface to all wooden tenon,a layer and a layer of CFRP vertical transverse reinforcement effect is best.The research results in this paper can provide some theoretical support and technicalreference for the repair and reinforcement of the ancient buildings in Huizhou,but also provide some reference for the repair and reinforcement of traditional buildings in other areas.
