木枋的轴向变形可通过销钉有效的约束。在受力过程中，销钉和木柱之间发生挤

The axial deformation of the wooden beam can be effectively restrained by the pin. <br><br>During the stress process, compression occurs between the pin and the wooden column, and the wooden column and the pin will be locally compressed, as shown in Figure 10.

The axial deformation of the wooden crucible can be effectively constrained by pins.<br><br>During the force process, the pin and the wooden column between the squeeze, the wooden column and pin will occur local compression, see Figure 10.

The axial deformation of wood brace can be effectively restrained by pin.<br>In the process of stress, the pin and the wood column will be squeezed, and the wood column and the pin will be locally compressed, as shown in FIG. 10.<br>
