【Abstract】 In this paper, the base isolated structure of three-dimension was simplified into a rigid plane model with three-freedoms. The equivalent stiffness and damping which are the parameters of the base shear method are got by the method of static condensation. In addition, a check formula limiting the aspect ratio of isolated structure is achieved.
