Abstract

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 selfcentering 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.
