Application of finite element analysis in the formal analysis of ancient architectural plaque section

Abstract Ancient architecture in Tibet has attracted considerable research attention because of its historical, religious, and artistic significance. Because the design and construction of ancient buildings often do not have the same detailed documentation as modern buildings, it is difficult to accurately simulate their structural properties. To study the structural performance of ancient buildings, the Tibetan ancient architecture structural performance analysis method based on finite element analysis is proposed. To better reflect the actual situation of engineering, the genetic algorithm is introduced to fine-tune the finite element calculation. The results of the experiments showed that the column compressive strain was maximum at 700 <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"> <m:mtext>με</m:mtext> </m:math> \text{&amp;#x03BC;&amp;#x03B5;} . Moreover, the plastic strain occurred only when the compressive strain reached more than 1,900, so the column was in the elastic strain stage during the process. When subjected to a vertical load, the upper part of the beam was compressed and the lower part was stretched. Furthermore, the lower part of the bow wood was stressed, and the upper part was stretched. The proposed method effectively improves the accuracy of the structural performance analysis of ancient buildings, and the results can be used for reference in ancient buildings.
