Calculation of Parameters of Buildings in Seismic Insulation System with Non-Linear Characteristics

چکیده
Seismic-protection measures make it possible to significantly decrease economical losses. Seismic shock absorption systems and seismic insulation of foundations and buildings can generally increase the reliability of structures. Calculations by Ja. M. Ajzenberg showed that relative horizontal seismic shifts of floors in seismically insulated buildings are significantly lower than in noninsulated buildings. Therefore, seismically insulated buildings are better protected from destruction during earthquakes. A method for calculating elastic oscillations of buildings in a seismic insulation system is used. Examples of calculations are presented so as to show the efficiency of the presented method and the necessity to consider these oscillations for high-rise buildings.
