Multi-storey Semi-Active Tuned Mass Damper building system Conference Paper uri icon

abstract

  • A multi-storey Semi-Active Tuned Mass Damper (SATMD) building system is proposed to control seismic response of structures. The application of using a structure's upper storey(s) as a tuned mass and a semi-active (SA) resetable actuators as central features of the control scheme is derived. The optimal tuning parameters are considered for the large mass ratio, for which a previously proposed equation is used and the practical optimal stiffness is allocated to the actuator stiffness and rubber bearing stiffness. A two degree of freedom model is adopted to verify the principal efficiency of the suggested structural control concept. Then 12- storey moment resisting frames are investigated to assess the viability and effectiveness of the system that aims to reduce the response of the buildings to earthquakes. The control ability of the SATMD scheme is compared to that of an uncontrolled and an ideal Passive Tuned Mass Damper (PTMD) building system. 2007 Taylor & Francis Group, London.
