| Summary: | Mortise connection is a unique way of connection in the wood structure of ancient buildings in China. This paper takes the mortise and mortise joints of wood window frame as the object. Eight models of wooden window frames are built in ANSYS software with the parameters of tenon diameter and tenon length. The static performance of them is studied. Through simulation loading, the ultimate bearing capacity of the model under vertical and horizontal loads is obtained, and it is concluded that the Mohr strength of the dangerous point and the maximum displacement value at the contact of the mullion and mullion are linearly related to the applied load. Through the parameter analysis, such as the diameter and length of mortise and tenon joint, the optimal design of this kind of mortise and tenon joint component are carried out so as to provide the theoretical basis for its application in the actual project.
