Effectiveness Of Seismic Base Isolation In Reinforced Concrete Multi-Storey Buildings, Ravshanbek Abdujabborovich Mavlonov, Sohiba Ergashboevna Numanova

Journal of Tashkent Institute of Railway Engineers

The dynamic reaction of a building to earthquake ground motion is the most critical reason for earthquake actuated damage to structures. The basic concept in seismic isolation is to protect the structure from the damaging effects of an earthquake by introducing a flexible support isolating the building from the shaking ground. Seismic isolation consists of essentially the installation of mechanisms such as isolators which decouple the structure from base. In the present study, the seismic response of the reinforced concrete building, base isolated by lead rubber bearings (LRBs) is compared with the seismic response of the same structure which does …
