摘要：
To improve the seismic resilience of building structure, self-centering structural components are systematically studied. The basic configuration and working principle of self-centering structural components are introduced, their research and development histories are summarized, and the existing problems and future development directions are analyzed. The results show that the self-centering structural components, including self-centering beams and columns, self-centering energy dissipation braces, and self-centering reinforced concrete/steel plate shear walls, exhibit flag-shaped or quasi-flag-shaped hysteretic characteristics, and can dissipate seismic input energy, ensuring the structural residual displacement ratio less than 0. 5%. The recentering materials in components consist of prestressed tendon and steel strand, fiber reinforced composite material bar, shape memory alloy, spring, etc. To promote the application of self-centering structural components in engineering, it is urgent to conduct in-depth research in optimizing configuration, increasing assembly level, improving seismic performance, resilience and durability, proposing application methods in novel structural systems, and establishing practical design and optimization approaches. © 2023 Southeast University.
