A Structural Engineer's principal responsibility is structural design. The design of essential building elements and components is the fundamental principle of structural engineering. The multistory structures are made to save money by expanding the building's floor size without expanding the surrounding land area. Low absorption value, lightweight, flexible, and higher buildings are the result of recent construction trends. During the vibrations the possibility of failure and problems with serviceability will be raised . Tuned mass dampers, or TMDs, have popular device for reducing these lateral vibrations during the earthquake and wind load . The present research uses a Response Spectrum Analysis of a realistic building model with TMD and without TMDs to assess the efficacy of TMDs in vibration management. Important Parameters such base shear, storey drift, maximum displacement, etc were examined. The results show that When actual earthquakes occur in buildings with TMD, there is a noticeable decrease in displacement and Storey Drift,etc values. Buildings that use TMD is better able to withstand the effects of earthquakes.
