Abstract

The paper presents the analysis of using tuned mass damper system modelled as pendulum tuned mass damper (TMD) for reducing the response of structure subjected to lateral force, such as earthquake action. The assumed steel eight-storey steel frame building is examined. The tuned mass damper system is modeled as 2 joint link in SAP2000, attached to top storey of the building. The effect of TMD system on structural responses for building under seismic excitation was evaluated by the results of maximum displacement and acceleration of the building. A sensitivity study of mass ratio showed that most effective case is TMD with mass ratio of 5%.
