Abstract
The Hanshin Earthquake inflicted big damages to many wooden buildings. The bad connection of column and bedsill has been indicated in one of the cause of increasing the damage. This paper reports on the results obtained experimentally on the resisting strength and deformation characteristics of tenon connection of precutting processing subjected to repeated lateral loading. The main results derived from the analysis of this experiment are as follows. In the modes of failure : The specimen of full tenon jointing and stub tenon jointing became loose due to the repeated-load, the specimen of cotter pin joint broke the root of tenon jointing, the wedge joint split from the cutting depth of the wedge, and the steel connector joint produced the tearing crack to the bedsill by the nail. The cotter pin joint and the steel connector joint are small extraction of the column from the tenon, it is an effective joining method for the extraction prevention of the column. Experimental value and calculated value are well correspondent to the case in which the strength of the wood material as the tenon jointing sank at 2mm was used. The estimate of ultimate strength of the tenon connection can be predicted by the equation proposed in this paper.
