Based on the failure model of rebars under seismic loading,the high strain and low cycle fatigue (HSLCF) behaviors of HRB500E rebar were tested systematically under constant strain condition.The statistical processing of HSLCF life tested were carried out using a double parameters Weibull probability function,and the HSLCF life with different confidence degree and the cyclic toughness with 95% confidence degree were obtained.Finally,the HSLCF mechanism and the ways to improve the HSLCF propertise were discussed.
