| Abstract: | 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. |

| Keywords: | corroded steel bars fatigue static tensile experiment corrosion ratio |
