As the structure height increases its response to seismic and wind loading also increases. Codes suggest that the forces and displacements of a structure are directly proportional to its height. A lot of research work is going on for reduction in responses during extreme loading condition due to wind and earthquake. Passive control devices like various types of dampers come very handy as they can be easily installed, requires no operation cost and are easily replaceable. These devices become active only when loading is applied. In this project we are going to study & discuss the reduction in response of a G+25 RCC commercial building when viscous dampers are used considering seismic loading and wind loading. Buildings with high ratio of its height to plan area will generate higher overturning moments while buildings with large plan areas may not act as expected due to differences in ground behavior (differential ground settlement) which are not always predictable. Torsion can be of great concern because of the eccentricity in the building layout which is not taken into consideration by the architects. Best type of bracing configuration, its location and comparison of dampers is to be studied. The analysis is done on ETABS 2019 and special emphasis is laid on reduction of displacement and storey drift. Keywords- Dynamic Analysis, Seismic Performance, Viscous Dampers I -INTRODUCTION Earthquake is the important term that comes to mind while designing any multi storey building. This earthquake are one of the most disastrous of natural criteria, This earthquake is known as „Along fault plane the vibration and shaking takes place at the earth surface due to underground ground motion. There is a huge loss of life, property and many essential services. For this we have to take care while constructing the building, the structure should be an earthquake resistant. The earthquake resistant structures are the structures which can resist the largest earthquake that can possibly occur in particular area as per the standard codes. The structure should be having a good building configuration than it is an earth quake resistant structure it should be having better lateral stiffness, ductility, lateral strength, stability and integrity .The structure to be made earthquake resistant many technologies are developed in that seismic control devices are now more widely used in buildings. Mainly there are three types of structural control systems, they are active energy dissipation system, semi active energy dissipation system, and passive energy
