摘要：

This paper focuses on the ductility demand of self-centering structures with flag-shaped (FS) hysteretic behavior under near-fault (NF) pulse-like ground motions. To this end, the general features of spectral regions for the NF pulse-like ground motion are first described. The effects of structural and ground motion characteristics on the ductility demand spectra are further carried out. The results indicate that the variation trends of the ductility demand spectra of the FS model are closely related to the spectral regions of the ground motion. Finally, a predictive model is established to evaluate the ductility demands for self-centering structures under NF pulse-like ground motions.
