[Abstract]:The compression deformation of wood will occur under the action of pressure in the transverse grain direction. there is a relationship between the volume of compression deformation and the compression area, edge distance and material thickness of the material. The deformation volume of the embedded area can be used to calculate the size of the embedded pressure, which is the theory of wood entrapment. According to the form of embedded pressure, it can be divided into uniform pressure and triangular pressure. Uniform pressure refers to the uniform distribution of embedded pressure in the embedded pressure area, triangular pressure refers to the triangular distribution of embedded pressure in the embedded pressure region. In the process of stress rotation of tenon and tenon joint of wood structure, most of the tenon embedded forms are triangular embedded compression. In this process, one of the resistance to prevent the tenon from turning is the embedded pressure, and of course the resistance also includes the friction caused by the slippage between the tenon and the morsel. Therefore, by studying the stress mechanism of tenon and tenon joints of wood structure, the bending moment rotation angle equation of tenon and tenon joint of wood structure can be established by using the relationship between embedded pressure and compression deformation volume. Because the compression deformation volume is related to the geometric size of the material, it is possible to study the parameters of the tenon and tenon joints of the wood structure. In order to realize this process, the author starts with the test of the previous research group, carefully observes the test phenomenon, thus establishes the geometric deformation relationship in the process of step tenon rotation, establishes the relationship between the length of the embedded pressure area and the rotation angle, establishes the relationship between the embedded pressure and the rotation angle, and finally obtains the bending moment-rotation angle relation of the step tenon in the form of rotating stiffness. The semi-rigid characteristics of tenon and tenon joints are studied. ABAQUS finite element software is used to simulate the whole test process in order to facilitate the subsequent parametric research. After observing the test phenomenon and analyzing the test data, it is found that the yield angle in the process of step tenon rotation is due to the embedded tenon compression yield, and the limit rotation angle is caused by the strength limit of the material at the tenon root. Therefore, in this paper, the Yamada-Sun strength criterion is used to analyze the tenon stress when the material at the tenon root reaches the strength limit.
