EXAMINATION OF EVALUATING PERFORMANCE OF ROTATIONAL RESISTANCE OF TRADITIONAL WOODEN HALF TENON JOINTS WITH DOWEL

This paper reports on an evaluation method of performance of rotational resistance of traditional wooden half tenon joints with dowel (Hana-sen). We constructed mechanical models for both the positive and negative directions based on the results of full-scale bending experiments and examined evaluation formulas for initial stiffness and yield strength. From the comparison and examination of the estimated values obtained from the evaluation formula and the experimental results, it was confirmed that a certain degree of consistency was achieved. And the yield strength of the calculated values tended to be similar to that of the real phenomenon.
