Abstract: Building structures are more susceptible to the ground motion and caused high level of damage to the lives and properties. Hence the safety parameters and the serviceability have to be maintained by reducing the induced seismic effect on the building structure. The aspire of this paper is to review a state of the art of researches on effectiveness of severalcontrol strategies such as, Semi-active Variable Damper, Magneto rheological (MR) dampers and piezoelectric friction dampers Resetting Variable Stiffnessalong with the controls strategies such asFuzzy Logic Control (FLC), ELM with LQG and Clipped Optimal Control Method Supervisory variable Fuzzy Logic Control(SVFLC) Skyhook Semi active control, Lyapunov Control. The benchmark problem on smart base isolated benchmark building developed evaluation criteria to compare among the control strategies along with the supplementary devices. Assimilating the performances of the control strategies it has been observed that the performance of MR damper with Supervisory Fuzzy Logic Control (SVFLC) is robust for all the earthquakes considered in the benchmark problem.

Keywords: smart base isolated benchmark building, control strategies, Magnetorheological (MR) dampers, piezoelectric friction dampers, Semi-active Variable Damper, Fuzzy Logic Control (FLC).
