     in recent decades, usage of the viscous dampers on retrofitting various infrastructures was considered. using this kind of energy absorption provide the conditions for clean retrofitting with minimal damage in retrofitting process. according to the construction of viscous dampers in iran and taken to the experimental analysis, this type of dampers in structural retrofitting process as a case study was used. nonlinear static analysis or pushover analysis is appropriate state for retrofitting design therefore, this analysis was used. in this regards, sap 2000 software for nonlinear static analysis was applied. the analysis in the using or not using of damper has been done separately. the results show that in case of using damper, plastic hinges of the structures remain in life safety domain but in case of not using damper, plastic hinges reach to collapse border and after that debacle to complete rupture. mann-whitney statistic test between created strain in elements with damper and without damper indicates that it is quite significant difference between the information. layout applied dampers in this project has been based on not create plastic joints that this issue needs to try and error and repeating the calculations to bring the proper results. with regard to the results achieved, retrofitting with viscous dampers was evaluated as ideal methods of retrofitting.
