摘要
总结了藏式建筑木构架典型的3种变形特征,依据前期勘察成果所确定的构件变形的关键点位置,提取数值模拟分析中关键点处的应变数值,研究典型藏式建筑木构架在梁的过度下挠、构件的扭转、雀替的歪闪3种情况下的变形关系,提出初步的变形破坏定位与判断方法,为结构状态分析提供科学依据.
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.
