将板齿视为弹性地基中的悬臂梁，建立了金属板式木桁架节点轴向和转动刚度值的分析模型。在给定木材比重、含水率、板和齿的几何形状以及加载条件的情况下，该模型可以预测轴向和旋转刚度值。为了验证模型的预测，对33个实际的拉伸接头和脚跟接头进行了测试。为了测试模型的范围，用木材比重从0.30到0.70，含水率从1到19%来制作接头。足跟关节上弦斜率12个月为3.5，12个月为5个。该模型的预测值在实验值的10%以内。
An analytical model that predicts the axial and rotational stiffness values of metal-plate-connected wood truss joints is developed by considering a plate tooth as a cantilever beam in an elastic foundation. Given lumber specific gravity, moisture content, plate and tooth geometry, and loading conditions, the model predicts axial and rotational stiffness values. A total of 33 actual tension splice and heel joints were tested to validate the predictions of the model. To test the scope of the model, joints were fabricated from wood specific gravity ranging from 0.30 to 0.70, and moisture content ranging from 1 to 19%. Heel joint top chord slopes were 3.5 on 12 and 5 on 12. The joints were tested by applying concentric and eccentric loads. The model predicts within 10% of experimental values.
