Abstract: Among all the disastrous events, for example, flood, twisters, typhoons, earthquakes, and drought the least comprehended and the most damaging one is earthquake. They are typically affected when rock underground break down along a fault and these seismic events are the most important natural hazards and can cause dangerous destruction by increasing the energy inside the structure. Since the forces applied on a structure are dynamic in nature, they cause vibrations inside the composition and they also increase the energy within the structural system. The major job of a structure is to take the lateral loads and carrying them to the foundation. Such undesirable energy can be dissipated by presenting the few control systems, for example, active, hybrid, passive and semi active control systems. The current work incorporates one such dissipating device called dampers. Dampers are the energy dissipating devices which are utilized to resist lateral forces acting up on the structure. They also resist the displacement that occurred in reinforced Concrete buildings during an earthquake. Dampers are utilized to decrease the buckling of columns and deflection of beams and to expand the stiffness of structure and furthermore used to moderate the vibration and twisting of RCC framed structure during earthquakes. There are various kinds of dampers utilized in general. In this current study fluid viscous damper (FVD) and metallic damper are used to resist the energy from earthquakes. Regular and irregular Models will be created with two dampers .i.e. fluid viscous dampers and metallic dampers and to carry out results such as storey displacement, storey drift etc. Different types of analysis methods such as time history analysis and response spectrum method are adapted to study the storey displacement on a G+20 storey RCC framed structure with dampers by using ETABS software. Performance of structures will be found by comparing the reactions as storey displacement and storey drift for regular and irregular structures. The present study compares the performance and effects on RCC frame regular and irregular structural systems by using fluid viscous and metallic passive energy dissipating dampers. These dampers will be used for different regular and irregular modelled structures and at different locations in a building and also in seismic zone V.
