Application of Isolated Technique in Multi-story Building

In order to promote isolated technique application in multi-story building and reduce the disaster of earthquake,the method of establishing and choosing the models of structure,designing the base-isolated layer and the actual meaning of dynamic character are discussed in conjunction with Code for seismic design of building(GB50011-2001).Then story shear models are adopted and the data is calculated and analyzed through MATLAB program,taking the real engineering as an example.Base-isolated structure will concentrate deformation onto the rubber bearing layer,and the acceleration and interlaminar shear of each floor will decrease.The result shows that the multi-story building that uses isolated structure can lower the earthquake reaction effectively,and ensure that it can be used normally in rare earthquakes.
