The Dynamic Analyse Of Interlayer Rubber Base Isolation

Earthquake is one of the disasters that harass human being all along. The main approach to alleviate the losing of life and belonging is anti-seismic engineering. The evolvement and improvement of anti-seismic design just is the ceaseless summarize and development process we realized that we thorough research and scientific practice. With the development of economic and social, the security and practicability of architecture anti-seismic design is required much rigorous, especially, with the high-precision development of modern industry, the traditional anti-seismic design sometimes cannot adapt to the demand of some actual engineering. Then some earthquake- engineering scientists have made some researches on isolator-seismic and damping-seismic and have made some progress. The papers whose research object is the 7-floor frame-structure with isolator-seismic layer, in which the isolator-seismic layer adopt some standard interlayer rubber isolator. By establish a 3-dimension finite-element modal and use the analysis soft-ANSYS, we can make dynamic analysis on the structure. By analyses we can get some response characteristics of the structure sparked by the normal and rarely earthquake of 8-degree fortify intensity, by the double-horizons seismic and by the vertical seismic. Summarized some questions that we should pay attentions when designing the anti-seismic structures. The results of this thesis can provide some theoretical basements for the design and permeation of the isolator-seismic frame-structure, and can provide some reference for the analyses and design of other style isolator-seismic structure, in the same time, because using of the interspatial modal, which is more advantageous than the plan analyses. By analysis and research, the aim of this thesis is to thorough open up the characteristic and superiority of the rubber isolator-seismic structure, consummate the design method of the isolator-seismic structure and promote the applications and developments of this technology in our country.
