In this paper, three types of moment resisting joints using drift pins are modeled into the three springs, and the relations between the moment and the rotation angle are calculated. The spring elements relating to the moment transfer consist of the connecting elements with the drift pins and the round bar of the tension side and with not only the same drift pin element but also the compressive strain inclined to the grain of compression side. The characteristics of the springs are evaluated by the experimental results in each element. The results calculated by the spring models are compared to the experimental results shown in reference 1). Furthermore the full-scale static loading experiments of the timber frame structure are carried out. Comparing the results obtained by the experiment to the results calculated by the spring models, the validity of the numerical modeling is confirmed sufficiently.
