Experimental Study of Viscoelastic Damper Model

During an earthquake a large amount of energy is imparted into the structure. To reduce the response of structure undergoing vibrations it becomes important for the structure to absorb or dissipate the energy. Basically there are two methods to improve seismic protection of structures primarily traditional methods increasing stiffness of structures (i.e. shear wall, bracings, and MR frames dual system) and secondary modern methods (i.e passive control systems, active control systems, semi active control systems and hybrid control system). Our focus is on passive control systems (Viscoelastic Damper). In passive energy dissipation systems the motion of structure is controlled by adding devices which modifies stiffness, damping or both. The present paper presents the comparison of the behavior of viscoelastic damper model with bare frame model. Inherent Damping, stiffness, acceleration, velocity and storey displacement are calculated and compared with bare frame model. Results and conclusions are prepared on the basis of study.
