Research Abstract	Shaking table tests of one-story box-shaped specimens using wood shear wall and wood moment frame was carried out four times (specimens). From the elastic plastic behavior of the structures having strength eccentricity, the following knowledge was obtained 1) When used with the shear walls and low strength frame, if there is sufficiently high strength to the frame, the structure has a high earthquake resistance 2) when used with the shear walls and frames with high deformation performance, if there is a certain degree of strength to the frame, the structure has a high earthquake resistance 3) Elastic-plastic behavior of the combined structure is traceable largely by the pseudo-three-dimensional analysis
