用于抗震韧性提升的自复位结构构件研究综述
Review of research on self-centering structural components for seismic resilience improvement
摘要
Abstract
To improve the seismic resilience of building structure,self-centering structural components are sys-tematically 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 de-velopment 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 con-crete/steel plate shear walls,exhibit flag-shaped or quasi-flag-shaped hysteretic characteristics,and can dissi-pate 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 engi-neering,it is urgent to conduct in-depth research in optimizing configuration,increasing assembly level,im-proving seismic performance,resilience and durability,proposing application methods in novel structural sys-tems,and establishing practical design and optimization approaches.关键词
