英文摘要：

The Tibetan Plateau has a unique natural environment and has a lot of different culture between Tibetan and mainland.These determine some of the basic features of the Tibetan architecture,and the structure form of the architecture also shows some different characteristics from the ancient buildings in the mainland.This paper summarized the three typical deformation characteristics of the timber frame in Tibetan architecture and extracted the strain values of the key points analyzed from the numerical simulation,where the key points were determined by the preliminary survey results.This paper also researched the deformation relationships of the timber frame in typical Tibetan architecture in the three cases including the excessive deflection of beam,the torsion of component and the QueTi’s tilt by using their strain values,and proposed the preliminary method of location and determination on the deformation damage.This method can provide a scientific basis on analyzing the data which come from the monitored actual structure.
