ANALYSIS OF MULTISTORIED BUILDING WITH AND WITHOUT TUNED MASS DAMPER

Abstract

During an earthquake the role of reinforced concrete buildings always critical because earthquake are most erratic and devastating of all natural calamities, which are the very difficult to save over engineering properties and life. Therefore we need to identify seismic performance of the built environment through the development of various procedures, which ensure the structures to withstand during the minor and major earthquakes events. A tuned mass damper (TMD) could be a device consisting of mass, spring, and damper that are attached to a structure in order to reduce the dynamic response of the structure. The frequency of the damper is tuned to a specific structural frequency so once that frequency is worked up; the damper can resonate out of section with the structural motion. The main objective of current work is to illustrate the effects of tuned mass damper using software ETABS 2016 and
analysis of the23 story structure with and without tuned mass damper. Results of these analyses are discussed in terms of various parameters such as maximum displacement, story shear. The comparison of these various parameters is done. We concluded from the results that displacement, story drift, and story shear decreases for structure with tuned mass damper.
