直榫节点木枋顶面和底面拔榫量-转角关系见图5，从图中可以看出，木枋顶面

Figure 5 shows the relationship between the pullout amount-turning angle between the top and bottom sides of the straight tenon joints. It can be seen from the figure that the pullout amount on the top of the wooden beam is a positive tensile displacement, which increases linearly with the increase of the turning angle. ; The amount of tenoning on the bottom of the wooden beam is the compression displacement, which increases linearly with the increase of the corner; and overall, the amount of tenoning on the top of the wooden beam is greater than that on the bottom of the wooden beam.

直榫节点木枋顶面和底面拔榫量-转角关系见图5，从图中可以看出，木枋顶面拔榫量为正向拉伸位移，随着转角的增大而线性增大；木枋底面拔榫量为压缩位移，随着转角的增大而线性增大；且总体上木枋顶面的拔榫量要大于木枋底面拔榫量。

The relationship between the tenon pulling amount on the top and bottom surface of the wood brace and the angle relationship is shown in Fig. 5. It can be seen from the figure that the tenon pulling amount on the top surface of the wooden beam is a positive tensile displacement, which increases linearly with the increase of the rotation angle; the tenon pulling amount on the top surface of the wooden beam is larger than that on the bottom surface of the wooden beam.<br>
