Seismic Behavior of Multi-Storey Structure Using Different Energy Dissipation Devices A-review

Abstract

Earthquake is a most disaster event, responsible a lot of structural damage and casualties worldwide on the earth’s surface without any early warning. The trends in using dampers in buildings and tall buildings, increasing yearly based on their outstanding feature during an earthquake event. Typically, there are four types of energy dissipation device system such as friction damper, viscous damper, viscoelastic damper and metallic damper. The theoretical and experimental study results indicate that all fourth types of dampers can be able to minimize the structural damages and cracking during an earthquake occurrence event. But only viscous damper device has an acceptable feature against of earthquake forces as compare to other kinds of damper devices in symmetric and asymmetric building plan configurations as well. Based on the reviews, a viscous damper device system plays major role in reducing the lateral displacement of buildings about 30% to 85%, inter-storey drift of building about 60% to 80% and 1487.82KN drop in base shear of structural components in symmetric and asymmetric building plan configurations upward as compared to friction dampers, viscoelastic dampers and metallic dampers. Contradictory, dampers can decrease the construction cost limitation of multi-storey structures economically rather than conventional buildings.
