Seismic isolated building structures are examined in this study. Triple concave friction pendulum (TCFP) is used
as a seismic isolation system which is easy to be manufactured and enduring more than traditional seismic
isolation systems. In the TCFP, take advantage of weight which pendulum carrying and it’s geometry in order to
obtain desirable result of seismic isolation systems. These systems offer advantage to buildings which subject to
severe earthquake. This is result of damping force of earthquake by means of their internal constructions, which
consists of multiple surfaces. As the combinations of surfaces upon which sliding is occurring change, the
stiffness and effective friction change accordingly.
A 2-D dimensional and eight stories of a building with and without isolation system are used in the time history
analysis in order to investigate of the effectiveness of the seismic isolation systems on the buildings. Results are
compared with each other to emphasize efficiency of the TCFP as a seismic isolation device. Additionally, the
mentioned TCFP is modeled as of a series arrangement of the three SCFP bearings.
