Current trends in construction industry demands taller and lighter structures, which are also more flexible and having quite low damping value. Now-a-days several techniques are available to minimize the vibration of the structure, out of the several techniques available for vibration control ,concept of using TMD is a newer one. This study was made to study the effectiveness of using TMD for controlling vibration of structure. The numerical stimulation are performed to study the structure with and without TMD. The soft storey will be made up of steel and its columns, beams, and slab sizes will be smaller than columns, beams, and slab sizes other stories of the building. The height, member sizes of soft storey will be devised based on the principle of TMD i.e. the natural frequency of TMD (soft storey) should have same natural frequency as that of main building. A twelve storied building with rectangular shape is considered for analysis. Analysis is done by FE software SAP2000 by using direct integration approach. TMDs with percentage masses 2%, 3%, 4%, 5% are considered. Three different recorded time histories of past Earthquake are used for the analysis. Namely 1940 EL-Centro Earthquake , Northridge Earthquake , and Taft Earthquake. comparision is done between the buildings with TMD and without TMD.
