A comparative quantitative assessment is carried out between the minimum drift criterion and minimum acceleration criterion for both near field and far field ground motions. The study reveals that significant anomalies are observed if the proportioning of the damper is carried out solely using the minimum drift based criterion, which is more common in practice. Both linear dampers and nonlinear dampers are used for the study; linear dampers for low rise structures and nonlinear dampers for medium and high rise structures. Linear time history analyses were performed for low rise structures equipped with linear dampers and nonlinear modal time history analyses were employed for medium and high rise structures with nonlinear dampers. Both far field and near field ground motions are used for the study.
