Effectiveness of tuned mass damper system for steel frame building

Abstract

The paper presents the analysis of using tuned mass damper system for reducing the response of structure subjected to lateral force, such as earthquake action. The assumed steel eight-story steel frame building is examined. The tuned mass damper system is modeled as 2 joint link in SAP2000, attached to top story of the building. The effect of tuned mass damper system for building under seismic excitation was evaluated by the results of maximum displacement and acceleration of the building. A sensitivity study was also performed to compare the structural response with different mass ratios. From the calculated results, discussions and conclusions are presented.
