Fuzzy Control Strategy for Seismic Response Reduction of Smart Base Isolated Benchmark Building

Control strategy based on fuzzy algorithm is presented for response reduction of the seismically excited base-isolated building, which is an eight story base isolated non-linear building similar to existing buildings in Los Angeles, California. When a control method based on fuzzy algorithm to a structure is used for vibration reduction, it has inherent robustness, easiness to treat the uncertainties of input data from the ground motion and structural vibration sensors and its ability to handle the non-linear behavior of the structure because of no need of exact mathematical model of the structure. This fuzzy algorithm is applied to both of active and semiactive control systems. The results of the numerical simulations show that the proposed control systems could be beneficial in reducing seismic responses of base isolated structures.
