Among the methods of passive control of buildings, the base isolation method seems to be the most effective. Its efficiency has been proven in the major earthquakes of the late twentieth century and early twenty-first century. The paper presents a comparative study between two seismic isolation systems. The first system is composed of high damping rubber bearings and of nonlinear fluid viscous dampers (HDRB+NFVD) and the second system is composed of friction pendulum bearings with two sliding surfaces (FPB2S). The study showed that the mean response relative displacements and also the base shear forces of the building with two isolation systems have close values. The minimum values of absolute acceleration response are obtained with HDRB+NFVD isolation system. Regarding the dissipated energy, the HDRB+NFVD isolation system dissipates more energy, than the FPB2S isolation system.
