The effect of scale ratio was investigated on a traditional dovetail post-beam joint with dimensional analysis. The dimensionless parameters for moment (M) are modulus of elasticity (E) and length (L), and the moment of a small-scale model is equal to the value calculated by dividing the moment of a full-scale structure by the cubed ratio. The theoretical results of moment resistance were checked among dovetail post-beam joints of different sizes. The average maximum and yield moment resistance increased as the scale ratio increased. However, when both moment values were divided by the cube of the scale ratio, the values were similar among the different scale ratio joints. This result shows that the moment resistance was satisfied with the dimensional analysis within the tested scale ratio and it would be possible to predict the structural characteristics by testing specimens with other scales.
