摘要: 针对钢筋在地震载荷下的失效模式,在恒应变条件下对HRB500E钢筋的高应变低周疲劳性能进行系统测试。利用威布尔双参数方法对疲劳寿命进行了统计分析,得出了不同置信度下的疲劳寿命和95%置信度下的循环韧度。并对疲劳机理和进一步提高高强钢筋高应变低周疲劳性能的途径进行了讨论。

Abstract: 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.
