It is rare to examine the dynamic stability of the Wooden Dwellings in case of earthquake. Thevefore there are few houses that the calculation on the stiffness or strength of the horizontal diaghrams was made. The purpose of this investigation is to clear the influence on the 3-dimensional behavier of the wooden structure subjected to the speification of the diaghrams. Then the racking experiments of the fullscale model was performed.The specimen of the tests was 2.7x6.3m wide and 2.7m high, and had two rooms. There were 4 bariations in the tests, 2 types in the wall specifications. and three types of the floor one. The basic specifications of the skeleton members followed the spec of Jutak-Kinyukoko. In the experiment, horizontal Loading was made at the top of each three walls. And the horizontal displacement was wesured to clear the torsion on the stiffness of the diaghrams.From the tests it became clear that the floor has enough stiffness to propagate the stress to the side walls even the floor has only Hiuti and no panells. And it was shown the distribution of the side walls stress was increased in order to the stiffness of the diaghrams.

地震作用下木结构住宅的动力稳定性研究尚属罕见。因此，很少有房屋对横截面的刚度或强度进行计算。本研究的目的是明确受图规范的木结构对三维性能的影响。然后进行了全尺寸模型的机架实验。试验试样宽2.7 × 6.3m，高2.7m，有两个房间。试验中有4种变化，2种类型的壁规格。地板有三种类型一种。骨架成员的基本规格遵循Jutak-Kinyukoko的规格。在试验中，在每三面墙的顶部进行水平加载。并对水平位移进行了测量，以消除对结构图刚度的扭转。从测试中可以清楚地看出，即使地板只有Hiuti而没有面板，地板也有足够的刚度将应力传播到侧壁。结果表明，为了提高图的刚度，侧壁应力分布增大。
