@article{(Open Science Index):https://publications.waset.org/pdf/6554, title = {Seismic Response Reduction of Structures using Smart Base Isolation System}, author = {H.S. Kim}, country = {}, institution = {}, abstract = {In this study, control performance of a smart base isolation system consisting of a friction pendulum system (FPS) and a magnetorheological (MR) damper has been investigated. A fuzzy logic controller (FLC) is used to modulate the MR damper so as to minimize structural acceleration while maintaining acceptable base displacement levels. To this end, a multi-objective optimization scheme is used to optimize parameters of membership functions and find appropriate fuzzy rules. To demonstrate effectiveness of the proposed multi-objective genetic algorithm for FLC, a numerical study of a smart base isolation system is conducted using several historical earthquakes. It is shown that the proposed method can find optimal fuzzy rules and that the optimized FLC outperforms not only a passive control strategy but also a human-designed FLC and a conventional semi-active control algorithm.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {5}, number = {12}, year = {2011}, pages = {2584 - 2589}, ee = {https://publications.waset.org/pdf/6554}, url = {https://publications.waset.org/vol/60}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 60, 2011}, }
