摘要
把三维隔振体系简化为三自由度平面刚体隔振模型.采用静力凝聚法,得出底部剪力法中参数———等效刚度及阻尼.提出了基础隔振体系高宽比限值的验算公式.
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.
