Abstract
One of the major concerns in structural engineering is the development of new design concepts to
improve structural performance and safety from the damaging effects of destructive earthquakes and
winds. With the intent to achieve cost-effective seismic-resistant constructions the structures must be
constructed to dissipate a large amount of seismic energy. Supplemental damping strategies are useful
for improving the seismic response of structures to natural and manmade hazards. Passive energy
dissipation devices, when integrated into a structure, dissipate a part of the input energy, thereby
reducing energy dissipation requirement on primary structural members and reducing probable
structural damage. The purpose of this research is to study the performance of building structure by
using passive energy dissipation devices. Different types of devices used in this study are hysteretic
dampers, friction dampers viscous and visco-elastic dampers. The finite element modeling technique is
used to observe the behavior of structure with dampers. Three prototype concrete buildings (3, 5 and
10 Story) with same configuration are analyzed with damper using time history analysis. The
buildings are analyzed with different types of dampers and by using different variation of their
properties along the height of the building and the responses of buildings are observed in terms of,
displacements, base shear and floor accelerations. It is found that the viscous and visco-elastic
dampers are more effective for 3 & 5 storey buildings while friction and hysteresis dampers are
effective for 10 storeys.
