000018371 520__ $$2eng$$aThe effectiveness of control strategies in achieving the objectives of a performance-based-design is well accepted in the earthquake engineering community. Consequently, various methods have been proposed for optimal design of dampers and their distribution along the building height. Most of the formulated methods concentrate mainly on reducing the responses with no explicit consideration of their long-term economic impact. In this study, a novel multi-objective optimization problem is formulated for optimally distributing viscous dampers by simultaneously minimizing the initial cost and the total expected seismic loss. An intensity based assessment is used for the computation of the total expected loss. The Pareto front between the initial cost and the total expected loss is generated by assuming the parent frame to remain linear. An adaptive aggregate gradient based multi-objective framework is employed to solve the formulated optimization problem. Implementation scheme of the optimization framework is outlined in detail. The efficacy of the proposed procedure is illustrated by applying it on a four storey reinforced concrete frame.
