Abstract

In order to investigate the most suitable tenon size of the mortise-tenon joint with pin, we carried out the static horizontal loading tests. The main results obtained from these tests and analytical investigations are as follows.
Mortisize-tenon joint thickness of which is 45mm improves the stiffness and strength by about 50% compared with that of using tenon of 30mm thickness. The analytical model shown in Fig. 19 expresses the stiffness and bearing force after yielding point.
