摘要
钢筋混凝土梁中钢筋腐蚀对疲劳的影响不容忽视,针对目前不同腐蚀下钢筋混凝土梁疲劳性能研究较少的情况,介绍了4种疲劳寿命评估方法,并以名义应力疲劳寿命评估法为理论基础,对国内以前做的部分钢筋混凝土梁疲劳试验结果进行了分析,采用应力幅作为钢筋混凝土梁的疲劳参数,取保证概率为95%,拟合了4种不同腐蚀下钢筋混凝土梁的疲劳S-N曲线,并进行对比分析,可为相关研究提供一定的参考。
Reinforcement corrosion in reinforced concrete beam fatigue can not be ignored, for the current different corrosion fatigue behavior of reinforced concrete beams less research, this paper introduces four kinds of fatigue life assessment methods, and nominal stress fatigue life evaluation method as the theoretical basis , previously done on the domestic part reinforced concrete beam fatigue test results were analyzed using the stress amplitude fatigue as a reinforced concrete beam parameters taken to ensure a probability of 95% , fitting four different corrosion of reinforced concrete beams fatigue S-N Curves and comparative analysis for relevant research to provide a reference.
