可从观察结果中得出明销直榫节点的变形形态是以木销钉为中心来发生变形，在

It can be concluded from the observation results that the deformation form of the straight tenon joint of the exposed pin is deformed with the wooden dowel as the center. At the end of loading, the local force of the mouth and the tenon exceeds the elastic yield strength of the wood along the grain and the transverse grain. The compression deformation is more obvious, and the relative rotation angle between the column and the beam is also increasing, and the maximum rotation angle can reach 0.22rad.

It can be concluded from the observation results that the deformation pattern of the open-pin direct slug node is centered on the wooden pin nail to deform, at the end of loading, the local force of the port and the hoe exceeds the elastic yield strength of the wood, the local compression deformation is more obvious, the relative angle between the column and the crucible is also increasing, the maximum angle can reach 0.22rad.

It can be concluded from the observation results that the deformation form of the straight tenon joint is that the deformation takes place at the center of the wood pin. At the end of the loading, the local stress of the mortise and tenon exceeds the elastic yield strength along and across the grain of the wood, and the local compression deformation is obvious. The relative angle between the column and the beam is also increasing, and the maximum angle can reach 0.22rad.<br>
