We proposed ultimate strength of the timber connection. Experimental variable are the effect in the tenon set by the reaction, tenon narrow side width in the pinned mortise, the double tenon jointing, nail length in reinforcement metal, etc. The result like the following was obtained. Experimental value can be estimated in writer's proposal. The case of the pinned mortise, the fracture of the tenon can be prevented by sufficiently ensuring the tenon narrow side width. The double tenon is effective for the extraction control. Whether the nail reaches in the tenon affects strength and extraction quantity. The effect by the reinforcement metal can be expected, when the nail doesn't reach even in the tenon. When it is constructed only in the nail, it is effective by the integration in the connection division, if it is the length that penetrates the tenon. And the nail can be sufficiently expected on the strength rise without using the reinforcement metal.
