Abstract: This study has been carried out to examine the performance of single and double tuned mass damper installed on top floor i.e 15th floor of the building in controlling dynamic responses of reinforced concrete structure. The building structure is subjected to four different past earthquake time history acceleration data in an order of their magnitude and duration. Non linearity in material has been considered as material property during analysis. A tuned mass damper is modeled as an additional floor on top floor and given mass ratio of 5% and assigned with link property. Nonlinear Time history analysis (Direct integration approach) has been performed in structure without TMD, with single and double TMDs using ETABS software. Performance of Single tuned mass damper (STMD) and double tuned mass damper (DTMDs) were determined by comparing responses of the structure without TMD, with single and double TMDs. Three results (displacement, Acceleration and Base shear) of the structure were considered as the performance criteria. Results indicate that tuned mass dampers are capable of decreasing structure responses, double TMDs have shown better performance than single TMD and the non-linearity in material have observed to increase the capacity of the structure to absorb more energy than linear material due to formation of plastic hinges which result in suppression of structural response.
