SEISMIC ANALYSIS OF BUILDINGS USING FLUID VISCOUS DAMPER

Now a day's Earthquakes are happening in various parts of the earth. So buildings should be designed and constructed in such a manner that they will withstand the earthquakes. Non linear seismic assessment is a good tool in helping us to predict the seismic capacity. Many devices are used to improve the seismic capacity of the buildings. In order to reduce the negative impacts of earthquakes, different kinds of protective system have been adopted in the structures worldwide. Placement of fluid viscous damper is one of the techniques in which it absorbs the shock vibrations of the building which causes damage. The effect of damper on the seismic response of the RC structures is studied in this. Little attention has been paid to evaluating the influence of the number and placement of dampers on the dynamic response Three dime nsional models are created using SAP2000. Time History analysis is carried out to study the effect of damper on the time period, base shear and acceleration in RC structures.
