A comparison between the ductility and energy dissipation capacity of SMRF and V-EBF systems

Special Moment Resisting Frame (SMRF) is one of the most well-known and practical Seismic Force Resisting Systems which has a high range of ductility and energy dissipation as well as producing enough space for the architectural design purpose of buildings or other structures. One of the most important deficiencies of this Seismic Force resisting System is the matter of controlling its maximum drift against the lateral force of earthquakes. So, it results in a non-economical design especially in tall buildings. Eccentrically Braced Frame with Vertical link beam (V-EBF) is almost a new Seismic Force Resisting System in which the vertical link beam has the role of the ductile member and has a wide range of ductility and energy dissipation capacity. In this paper, the ductility and energy dissipation capacity of SMRF system and V-EBF system are compared. For this purpose, a number of these two systems with different characteristics are analysed by non-linear finite element method under cyclic loading and the results are compared
