Abstract

Two-particle simplified calculation model of inter-isolated structure is proposed.In the meantime

simplified formula of model parameters is derived based on the study of two aspects

including dynamic characteristics of two-particle simplified calculation model and the sensibility of seismic responses to the quality ratio and period ratio of model.In order to verify the reliability and practicability of research results proposed in this paper

an engineering example is put forward based on the comparative calculation analysis.The results show that dynamic characteristics of the inter-story isolated structure are closely related to the quality ratio and period ratio of the upper and lower structures

and also reflect the characteristics of higher order modes in the interstory isolation.The simplified formula presented in this paper can quickly estimate the seismic response in isolated layers and the upper and lower structures adjacent to the isolated layers.This method generated from the dynamic characteristics of two-particle simplified calculation model has a clear concept

simple calculation logic and certain accuracy.
