One of the methods that has been considered in recent years for retrofitting the concrete buildings is the use of eccentricbraces with single and dual vertical links. In this dual system, if the link member is correctly designed, it can have a function similar to metallic dampers. In this study, the effect of lateral load patterns on the seismic performance factors of this dual system (RC intermediate moment frames retrofitted by eccentric braces with single and dual vertical links) is investigated. For this purpose, three RC intermediate moment frames of 4, 8 and 12 stories were modeled and designed using the Standard No. 2800, second edition. In order to assess these buildings under modified loads, they were reloaded according to the Standard No. 2800, fourth edition. The results showed that the stress ratios in most of the columns were larger than one. Therefore, the buildings were retrofitted using the eccentric braces with single and dual vertical links. Then, static nonlinear analysis (pushover) was performed under the 6 different load patterns and the seismic performance coefficients were calculated. The results show that with increasing the height of buildings, the R factor increases for all load patterns. Also, the R-factor obtained using the rectangular load pattern is conservative.
