This paper presents the results and discussions from the lateral shear loaded experiments of typical earth-walls, especially kokabe-wall, in Kyoto town-house. The maximum load of a timber frame with a kokabe-wall was about 1.9 times larger compared to those without it. The stiffness of the wooden frame alone was evaluated by using the physical characteristic model of embedment at Hozo(tenon) and Nuki-joint. Further, the stiffness of the kokabe-wall alone was evaluated by using shear stiffness and young modulus of earth-wall. Final stiffness of the total structure was achieved by combining the two stiffness.
