Performance Analysis Of Large Multi-conditions Isolation Test

For a long time,Anti-seismic concept has been leeding the human engineering design and gradually developed a series of efficiently seismic-design theory and method. However, in recent years the high frequency of large earthquakes has gradually attracted people to rethink the system defects of seismic design concept.This paper is based on "large base isolation test" independently designed by professor Chen Qinglai. All of the data in this paper is the first test data from this Large-scale isolation test.This thesis can be summarized as the following three levels:The first part describes isolated thought in seismic dominant engineering field and the process it formed as the historical inevitability.secondly, the paper provided advanced vibration theory,the theoretical support for the modern Earthquake-Isolation technology. Finally, relying on above two parts I chose and analysed two working conditions of eight degree and nine degree of rare earthquake added to the test model.I got the seismic acceleration, seismic response speed of1-6layer through the MATLAB analysis software with the preliminary schedule obtained. And then,the paper got the conclusion of vibration isolation effect in above two conditions.
