000021660 520__ $$2eng$$aA numerical study of the seismic response of base isolated free standing monolithic ancient column is presented in this paper. These rocking structural systems are analyzed standing free on an isolated base supported on friction pendulum (FP) bearings. Specifically, the implementation of multi-spherical friction bearings is examined. The rocking columns as well as the friction pendulum bearings were simulated using finite element method. Of particular importance is the detailed modeling of the isolators, which seismic behavior are validated. It is known that subjected to lower predominant period excitations, free standing rocking blocks exhibits increased stability. While, they are vulnerable to long period excitations. That opposes to the main characteristic of the base isolation technic which is to elongate the oscillation period. Thus, a thorough investigation of the influence of the FP bearings radius on the seismic response of free standing columns is caring out, to result in optimal design of the isolation devices in order to avoid rocking overturning.
