Abstract - Structure are lifeline to our modern world. We as
in the structure. These oscillations produced at the base are transferred to the top of structure which may prove disastrous for the structure.
human are dependent on them to commute, to work, or to power our economies. As India grows further, more and more different types of structures will be required whether it is for accommodation, Housing, warehouse, office spaces or more. As civil engineers, it is our duty to make sure that we design and construct our structures responsibly, and efficiently so as service to our needs. As we know, in Delhi, the major natural disaster that occur is earthquake. So, an earthquake is the only disaster that can cause harm to our structures. Thus, it becomes utmost important that we pay attention to earthquake resistance by building or how our structure could survive a possible earthquake and seismic wave. So, it is very important to carry out seismic analysis of structure in this case a building. We are here interested to learn and apply the fundamentals concept of seismic analysis and to learn about the application of the use of fluid viscous damper that help dissipates and absorb seismic waves itself, thus protecting the structure. The use of dampers that actually work as energy dissipators have been taken up to meet the safety and serviceability requirements of structures.
The basic aim of this paper is to find optimum methods that would decrease or control these vibrations and enhance the safety of the structure. For it, we will be doing detailed analysis by carrying out comparative study of four models using 5 earthquake ground motion data. For this we do Pushover Analysis, Response Spectrum and Time History. We try to differentiate the best most optimized floor position for damper results with the least.
2. LITERATURE REVIEW In recent years, a lot of literature work has been done with regards to the safety and serviceability of structures. The conventional approach to the construction of earthquake resistant structures depends on the construction of buildings with enough strength, stiffness and inelastic deformation capacity that can withstand the amount of vibrations and oscillations caused by the earthquake in the structure.

Prof Y. G. Zhao and T. Ono (2001) noted about “second strategies for structural reliability” in which they said, to perform a correct analysis a structural engineer ought to decide such information as structural hundreds, geometry, guide conditions, and materials properties. The effects of such an analysis normally encompass assist reactions, stresses and displacements. This record is then compared to standards that imply the situations of failure. superior structural evaluation may additionally study dynamic reaction, balance and non-linear behavior.
1. INTRODUCTION In the present era of high population, construction of highrise buildings is becoming the need of the hour. With massive work going on in construction sector, utmost priority is given to safety and serviceability of structures. The seismic waves produced by earthquakes pose a major threat to the safety of structures. To counter this, the use of energy dissipating devices has been encouraged in the construction setup. These energy dissipators, technically known as dampers enhance the safety of buildings. This paper deals with comparative structural analysis of structures both with and without dampers, using different software tools like ETABS and thereby getting a view of the efficiency in the safety of structure by the introduction of dampers.
H.kit Miyamoto et al, (2013) Studied the use of four story industrial building. For three-D mathematical fashions SAP software program is used. Nonlinear fvd is employed to regulate memories go with the flow. Nonlinear time history executed to decide performance. two tiers of seismic risks investigated first (MCE) and 2d one (DBE).in the end the most response quantities which include displacement, acceleration, and tale shear evaluated. D.Lee et al (2001) an in-depth summary given on working method of FVD, installation method, and its future scope. In this paper effect of linear and non linear damper and their relationship studied. Various software like SAP and ETABS
The earthquake creates vibrating forces at the base of the structure, which in turn result in the creation of oscillations
