This study examines the effects of common viscose damper on the behavior of adjacent reinforced concrete structures. For this purpose, three reinforced concrete buildings with 3, 5 and 7 floors and a regular plan were selected and were compared in two cases with and without viscous dampers at the seams. They are designed based on discussions of Buildings Regulations 2800 and the 6 and 9 issues of Iranian National Building Regulations. Those buildings that were under the analysis of accelerograms of Bam, Mangil and El Centro, are then analyzed with nonlinear modal time history. The accelerograms before applied to the structures are scaled based on the 2800 Regulations. Those buildings were modeled by SAP2000 finite element modeling software. Linear behavior of structural components of said structure and the non-linear behavior of viscous dampers were modeled. Finally, the seismic response of the buildings includes the base shear force, up to a maximum lateral acceleration of seismic classes. Classes for both with and without the viscous damper have been extracted and compared. The results showed the reduction in relative lateral displacement, maximum acceleration and base cut applied to a structure in the presence of viscous dampers between two structures. This decline is not even in the direction that the viscous damper is viewed as significant.
