Abstract

Application of dampers as means of attenuation of earthquake energy is one of the most significant approaches and viscose damper is the most popular one. The aim of this paper was to investigate the effect of viscose dampers on decreasing the vulnerability of tall structures at earthquake and selection of the optimal arrangement of dampers in these structures. so, two types of concrete special moment frames with central cores with 26 floors were designed with SAP2000 software. Then, they were applied to five earthquake records and their vulnerabilities were investigated according to non-linear timehistory dynamic analysis. Then, dampers were erected into the structure and modeled. To do so, the dampers were horizontally positioned in the structure and the models were evaluated again using non-linear timehistory dynamic analysis. The results obtained by investigating three parameters of maximum Floor displacement, base shear, and structure Acceleration verified signified decrease in all three parameters. In such a way that the displacement of the structure, between 10 to 25 percent, the base shear 15 percent, as well as the acceleration of the input to the structure, to about 17 to 20 percentage reduction.
