Abstract
ABSTRACT This paper investigates the performance of the Magnetorheological damper as a smart dissipating device in the isolated buildings for prevention of seismic pounding. To that end, an isolated building was modeled by considering the pounding effect with different gap distances. Multi-objective optimization was performed to optimize the fuzzy logic control of damper for each gap distance. The results showed that the optimized semi-active control system can prevent the pounding of the building and greatly improve the structure’s behavior as compared to the isolated pounded building and even to the case without the pounding at some considered gap distances.
