Analysis of High Rise Structure using Tune Mass Damper

Tall Buildings are increasing day by day built all over. As safety of users is the importance prime factor, so the structural stability is the main concern of Structural Engineering. Most of the structures are found to have very low natural damping. In order to increase the damping capacity of a structure various mechanical means to increase damping are being considered now days in high rise buildings. A Tuned mass damper (TMD) is a device consisting of a mass, and spring that is attached to a structure in order to reduce the dynamic response of the structure. For Analysis purpose symmetrical moment resistance frame (MRF) of 10th, 15th, 20th, 25th and 30th storey are modeled with and without tuned mass damper by using software ETABS. A tuned mass damper (TMD) is placed on top floor of building and Linear static analysis is perform. The result obtained from software analysis of 10th, 15th, 20th, 25th and 30th storey building with and without tuned mass damper are compare with each other.
