Seismic Performance of RC Building with X-plate and Accordion Metallic Dampers

The supplementary energy dissipation represents an efficient technique for the seismic protection of structural system. Metallic damper such as X-plate and AMD is among energy dissipating devices that have been using in the new generation of earthquake resisting building. In this paper, the performance of building with X- plate and AMD made of Steel are investigated to check effectiveness of damper material. For this purpose ground acceleration records, Loma Pieta is used as the disturbing ground motion for time history analysis and entire analysis is carried out by using SAP2000. .The structure has been analysed without dampers and with full dampers and then after analysis, the response quantities such as maximum displacement, max interstory drift, axial force, shear force and bending moment has compared. The result obtained after the analysis shows that the response quantities are reduced significantly and it has been concluded that, these devices are very much effective to dissipate the external energy.
