Seismic resistance increase of operated buildings using special seismic protection devices
Abstract
Abstract In recent years, seismicity has been increased several times in the Russian Federation. The situation exerts a significant effect on the seismic resistance of existing facilities. It is known that buildings can be reinforced by using various methods among which unconventional seismic protection devices that include seismic isolation and seismic damping hold a special place, being efficiently used not only in newly built buildings, but also in operated ones. Unconventional methods implementation of the seismic resistance increase in operated buildings is shown using specific examples. Rubber-metal supports, dynamic absorber and rubbing friction dampers are used. Recommendations on their specific use to improve buildings seismic resistance are offered.
