In this study the time history analyses are carried out three dimensionally for a simple five-story concrete
structure seismically isolated incorporating triple friction pendulum bearings with different sliding surface
properties with the help of the ABAQUS finite element program. The altering friction surface properties are
friction coefficient and radius of curvature. The performances of the various isolators are compared with
each other as well as with those of a fixed based structure. For this purpose, maximum relative story
displacements, story accelerations and column base shear forces are investigated as seismic reactions.
According to the analysis results it can be stated that the seismic reactions of isolated structures are
significantly reduced when compared to those of the fixed supported structure. Additionally, when triple
friction pendulum bearing isolators with different friction coefficients and friction surface radii are
compared, it can be observed that increasing the friction coefficient increases the reactions of the structure
while increasing the friction surface radii decreases the reactions.
