Abstract
Conventionally, the structures are designed to resist dynamic forces through the combination of strength,deformability and the energy absorption. These structures deformwell beyond elastic limit in a severe earthquake. The extent of damage the earthquake maycause to the structure may depend on severity of the earthquake, distance from the epicenterand many other factors. The damage can be reduced by proper analysis and design of thestructure. To avoid the damage of the structure due to conventional ductility based design,Structural engineers are working to figure out different alternative systems that could berobust and can withstand strong motions. Energy dissipation devices is one of the system thatwork by absorbing or reflecting a portion of the input energy that would otherwise betransmitted to the structure itself and would damage the structure. In such situations structuralcontrol techniques are more promising for earthquake resistant design. The concept of thesetechniques is to absorb the vibration energy of the structure and hence reduce the stresses inthe structure.
