ANALYSIS OF TUNED MASS DAMPER IN HIGH-RISE STRUCTURES

Abstract

The present work aims to demonstrate the performance of building. Here, models of 15,25 and 40 storeys without and with TMD were prepared by considering symmetrical R.C moment resisting frame. Tuned Mass Dampers with varying mass ratio of 3% applied. Analysis of NLTH is done utilizing 1893:2002 for designing a RCMRF structure for seismic force and gravity load. It has been proposed to develop a suitable TMD that should be effective enough to reduce base shear, story drift, story displacement etc. for doing so optimal parameters of TMD where calculated using Den hutong's equation and parameters like frequency ratio, damping ratio, effective stiffness of TMD and effectual TMD damping. Using this parameters TMD was modeled in SAAP 2000 and result where
compared with TMD and without TMD.
