In recent years, considering vertical movement in structures, which is known as self-centering motion, is one of the methods used to dissipate the earthquake energy. In this study, 4-, 8-, and 12-Story steel structures with special concentrically braced frame (SCBFs) and eccentrically braced frames ‎(SEBFs) ‎were considered in order to investigate the effect of self-centering ‎motion under seven near-field earthquakes using Sap 2000 software. The results of this research indicate that considering the self-centering ‎motion, the behavior of structures are changing in SCBFs and SEBFs. In ‎, 4-, 8-, and 12-Story SEBFs structures with considering the self-centering ‎motion, the column and bracing ‎forces were increased which this was different with SCBFs ‎ structures. Considering the self-centering ‎motion, more plastic joints are formed in the beams. Therefore, in the self-centering ‎of the columns, the beams outside the bay are more affected. In general, the results indicate that the self-centering ‎motion is better in the SCBFs.
