According to experimental research on 10 specimen of steel bars under fatigue loading, remained static strength of bars has been measured. On the base of experimental data, a new fatigue strength (limit) measuring method of steel bars using in concrete structure has been set up. Experimental results and theoretic analysis show that the method can shorten time in experiment, reduce discreteness and improve the precision of data. The method may be used to measure fatigue limit of both not corroded and corroded bars (especially with local unsymmetrical corrosion pits) bearing fatigue loading, therefore it will be used to evaluate the residual fatigue expectation of reinforced concrete that bearing fatigue loads such as bridge structure which has served for a certain long of time and be used to make right decisions on repairing or removing structures under reversed loads.
