Abstract:
In order to explore the fatigue performance of corroded reinforced concrete(RC) members,the bond-slip performance of corroded RC members under cyclic loading is experimentally researched.The influencing rule of corrosion rate on the bond behavior degradation of RC members under the fatigue load is analyzed.The result shows that the ultimate bond strength and the slippage rise at first and then drop with the increase of the corrosion rate under the same fatigue load.The ultimate bond strength rises when the corrosion rate is lower 2% and drops when the corrosion rate is higher 4%.Based on the test data,the computation formula of the ultimate bond strength is obtained,and the computation result agrees with the test data.
