Abstract: Self-centering steel frame structures are advantageous in that they can control structural damage,reduce or eliminate residual deformation, and are easy to repair after strong earthquakes. Aself-centeringprefabricated steel frame with a column base connected by semi-rigid joints (SPSF-SRJ) is proposed in the presentstudy. The goal is to address the problem of excessive plasticity that a self-centering prefabricated frame with acolumn base connected by rigid joints exhibits. In addition, a pseudo-dynamic test is performed on the sub-structureof the proposed system to investigate and discuss the seismic performance of the system, which is then comparedwith the seismic performance of a self-centering prefabricated steel frame with a column base connected by rigidjoints (SPSF-RJ). The test results show that the proposed performance-based design goal can be realized in theSPSF-SRJ. The semi-rigid joints effectively protect the column base and eliminate or reduce the damage to thecolumns; after an earthquake, only the steel beams require repairs, which significantly reduces the post-earthquakerepair cost.
