During the attacks of seismic, the movement of ground is transmitted to the constructions via their foundations; if the ground could move freely under the works; this movement could not be transmitted. In this context emerged, these last years, the idea to introduce between the ground and the buildings a filter, allowing dissipating the maximum of energy, and located large deformations on this filter. This strategy called seismic isolation. Among the goal of the effectiveness of these devices of seismic isolation in the dissipation of energy induced by the seismic, a comparative study was carries out in this article on the answers of structure of 8 story with system of seismic isolation (LRB) and other structure at fixed base.
