Abstract
Predominant ground motion frequencies and spectra could differ sufficiently at different earthquakes on one site. The reasons of the differences are the epicenter distance, the focal depth, and many others. As it is well known, the frequency spectral configuration and predominant frequency values influence the structural seismic response and seismic behavior of structures (Mexico earthquakes 1957, 1962; Bucharest, 1977, Spitak, Armenia, 1988 and other). The maximum seismic response depends of how close the fundamental frequency values of the structure are to the predominant ground motion frequencies. Seismoisolation as an effective approach to seismic response control became popular recent decades in many countries. The conclusions of RCEE analytical and experimental studies are that in abovementioned cases when different spectra and predominant frequencies could be expected at a given site structures with changing (self-adjusting) natural frequencies could be effective for adaptive seismic response control. Several dozens of structures with switch-off reserve elements are designed with RCEE participation and constructed in Siberia, in Caucasus, near Lake Baykal and at other earthquake dangerous areas of Russian Federation. Besides, of pile-in-tube foundations also other structural systems are constructed. Among these systems are rocking supports with reserve switch-off elements, flexible columns with switch-off reserve rigid elements,pile-in-tube, sliding supports and others.
