Wood-to-wood joint is generally used on Japanese traditional timber buildings. Traditional timber buildings have been constructed based on empirical rules and craftsmanship of carpenters. In these days, scientific analysis of traditional timber jointrequires a further progress. It is necessary to reveal a strength properties of the joints. This study discusses the three types of joint (Sya-chi-sen joint, Komi-sen joint and Hana-sen joint) for evaluation of their tensile performance. The final purpose is to propose a mechanical model. Furthermore, a material test was carried out in order to clarify the mechanical properties of live oak that have been used as a fastener.
