Self -centering steel structural systems not only can reduce even eliminate the post-earthquake residual deformation,but also can increase the energy dissipation capacity by combining with the energy-dissipation devices.Therefore,this type of systems are promising for engineering application.Components and basic characteristics of the self-centering steel structural systems were introduced briefly.New proposed self-centering steel structural systems were categorized as self-centering steel frame system,self-centering steel braced-frame system,self-centering steel plate shear wall system and self-centering energy-dissipation devices. Configurations,rationale and current research status of each system were summarized detailedly.Further research issues that are necessary for the development of self-centering steel structural systems are recommended.
