In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant or various upper limit and low limit of force or stress has been extensively used. But this kind of test means can't be used to study the behavior of concrete low cycle fatigue under large strain.

It was found that the low cycle fatigue character has close internal relations with the high cycle fatigue character. In the research of high cycle fatigue of concrete, the test means of cyclic loading between the set constant of force or stress has been extensively used. But this kind of test means can't be used in studying the behavior of concrete low cycle fatigue under large strain.

在研究中发现低周疲劳特征与高周疲劳特征有着密切的内在联系，但高周疲劳问题研究中使用的是在设定的力或应力的上下界限之间重复受力的试验方法，这种方法已无法用于混凝土高应变低周疲劳性能的试验研究。

This study consists of three parts. Firstly the equivalently accelerative corrosive environment is determined through the analysis of statistic data of corrosion environment. Secondly the fatigue test is carried out under the constant amplitude cyclic loading for the specimens which are exposed in the corrosive environment for equivalent calendar time of zero year, 3 years, 8 years and 13 years. Four S-N curves with different corrosive time are obtained based on the fatigue experiment. Finally the regression method of S-N curves for experimental data is researched and a weighted least square fit is put forward in which the weigh of a group of test data is inversely proportional to the length of the confidence interval.
