The use of vertical links in eccentric braced frames, in addition to special system privileges, is one of the best methods of passive structural control. Past studies regarding the reduction factor of aforementioned systems are valuable but limited. The purpose of this study was to understand the mechanism of failure in frames equipped with vertical links, during which, while defining and elaborating the estimation steps of demand and capacity reduction factors, these two parameters have been evaluated for 4 and 8-story building frames with the aforementioned systems. The distinction between the present study and other similar studies of reduction factor estimation is multilevel assessment based on seismic demand and frame capacity. Based on the results, the system has high ductility, so that the use of design reduction factor up to 8 will also provide reasonable seismic reliability for frame buildings under the medium and high earthquake intensities.
