摘　　要：通过对疲劳试验后的锈蚀钢筋混凝土梁中锈蚀钢筋的静力拉伸试验,获取相应锈蚀钢筋的力学性能参数,经分析得到钢筋锈蚀率与疲劳寿命和名义屈服强度之间的定性关系以及钢筋静力力学性能随疲劳应力幅和锈蚀率的变化规律。The corroded steel bars, which are taken from the beams destroyed by the fatigue loads, are tested in the static tensile experiment. Then the obtained correlative mechanics parameters are analyzed to attain the relationship of the corrosion ratio, the lifespan and the nominal yield strength of the corroded steel bars. The steel bars＇ static mechanical property transforms with the variation of fatigue stress amplitude and the corrosion ratio of bars.
