Abstract - Here we implemented high rise structure
usually slowly acts on structure, but seismic load act rapidly and vibrate the structure.
construction everywhere as we have urbane designing software and due to improvement in the field of engineering and technology. As we know if we rise height of building seismic and wind load response also increase. Indian standard codes propose that the displacements and forces of a structure are directly relational to its height. Continuously study is going on for reduction of response during extreme horizontal loading due to shaking and wind. Passive controller device like various type of dampers is used for controlling response of shaking and wind load.
What is earthquake resistant building?
Earthquake resistant building is defined as there is no damage allowed in structural member and no major damage allowed in non-structural member in weak earthquake, Structural damage allowed but not major damage allowed it should be repairable in moderate or moderately strong earthquake, and in strong earthquake major damage allowed but structure should not collapse during earthquake, this type of building known as earthquake resistant building.
Key Words: Fluid viscous dampers, Displacement, Storey Drift and Storey shear, ETABS.
What is damper?
1. INTRODUCTION
“Dampers are energy dissipation system”.
1.1 General
Dampers are device used to disperse or absorb vibration resulting from earthquake in the structure to increase the damping and stiffness of the structure.
Which different kind of load is acting on RC building?
There are many types of loads are acting on RC building. If we discus majorly in India we consider Dead load, Live load, Seismic load and Wind load (if height if building is more than 10m, as per IS 875 part 3). But according to IS 456 table-18 while we consider earthquake effect then in given load combination wind load is substitute by earthquake load. Dead Load:

1.2 Fluid viscous dampers:
Dead load is mainly caused by the individual weight of the structure and the completion of the structure. Dead loads are carried out only in the vertical direction. We can only assume that no tipping occurred due to static properties. Live Load: Live load is acting due to human stay in building, furniture, vehicle etc. In different type of building, we consider different value of Live load as suggested in IS 875 part 2. Earthquake Load (Seismic load):

Seismic load is the horizontal load on the building as result of the shaking of the ground during an earthquake. Earthquake loads are “dynamic load”. Other types of loads
