Abstract

Energy dissipation devices such as Fluid Viscous Dampers have proved quite effective in safeguarding the buildings in the event of an earthquake. This study has shown optimized usage of these devices as regard to total amount of supplemental damping provided in context of multiobjective optimized response control. Base shear and interstorey drifts have been used as important multiple control parameters to implement the optimization strategy for supplemental damping. Amongst several optimization algorithms the genetic algorithm has created its niche over last three decades in every field and is followed in this study. Dynamic analysis is carried out with strong ground motions which have shown excessive damage to buildings in the past and their effect on set of five and ten storey buildings is investigated and presented.
