| Abstract: | In this paper, a new useful and simple mode is suggested for the design of the earthquake resistant structure with base isolation system. By using this mode, the relationship between the respone of upper structure and base, also some parameters are obtained. These parameters include the natural frequency of upper structure, the stiffness and damping of bearing, and dominate period of earthquake etc. Further, the optimization damping values on all range of frequency of structures will be got using analytical method suggested by authors. The example shows that, this method is reliable, accurate, useful and simple, and is able to be used for the engineering design of the base isolation system. |
