Constant ductility inelastic displacement ratio spectra of shape memory alloy-friction self-centering structures based on a hybrid model

Previous researches on the constant ductility inelastic displacement ratio spectra (\({C}_{\upmu }\)) of self-centering structures have been conducted based typical flag-shaped (FS) model. However, arising shape-memory-alloy-friction (SMAFSs) own their specialized force–displacement relationship different from FS In this research, a hybrid model composed and Coulomb friction is employed an efficient calculating procedure proposed to statistically investigate \({C}_{\upmu }\) SMAFSs. Comparison with system similar capacity shows that SMAFS significantly system, which explains necessity employing for SMAFSs effects friction. The seismic parameters structural are investigated. Furthermore, formula estimating through statistical regression. This could estimate describe more accurately. research provide basis obtain reliable design results structures.
