摘要：

通过不同锈蚀率下不锈钢筋混凝土试件的中心拉拔试验，分析锈蚀率、锈胀裂缝宽度对不锈钢筋/混凝土黏结性能退化的影响规律，分别基于质量锈蚀率和表面裂缝宽度建立不锈钢筋与混凝土黏结强度的预测公式，并与普通钢筋混凝土黏结性能进行对比分析. 研究结果表明：类似普通钢筋混凝土黏结退化规律，锈蚀不锈钢筋黏结强度随锈蚀率增大呈先增后减趋势，但拐点锈蚀率较普通钢筋更大；不锈钢局部坑蚀具有较强的随机性，使得锈胀裂缝宽度与锈蚀率的关系较为离散，与基于锈蚀率的黏结退化模型相比，基于表面锈胀裂缝宽度的模型可以更好地预测不锈钢筋与混凝土黏结强度的退化规律，工程实用性更强；在相同锈蚀程度下，不锈钢筋黏结强度退化程度较普通钢筋小，现有的普通钢筋黏结退化模型可以用于不锈钢黏结强度的预测，具有一定的安全保证.

Abstract:

The direct pullout tests under different corrosion rates were conducted to evaluate the bond performance between the corroded stainless steel bar and the concrete. The influences of corrosion rate and surface crack width on the bond degradation were analyzed, and then predictive formulas of bond strength between the stainless steel bar and the concrete were given respectively based on the corrosion rate and the surface crack width. The differences of bond properties between ordinary and stainless steel reinforced concretes were compared. Test results show that the bond strength between corroded stainless steel bar and concrete increases firstly and then decreases as the increase of corrosion rate, which is similar to that of the ordinary reinforced concrete, however the critical corrosion rate of stainless steel affecting the bond strength is higher than that of ordinary reinforcement. Pitting corrosion has strong randomness, which leads to the discrete relationship between the corrosion crack width and corrosion rate. Compared with the model based on the corrosion rate, the predictive model based on the surface crack width has a better agreement with the test results, and is of better practicability. The degradation amount of bond strength of stainless steel reinforced concrete is smaller than that of ordinary reinforced concrete at a same corrosion degree. The existing bond degradation model of ordinary reinforced concrete can be used to descript the stainless steel reinforced concrete directly and has a certain safety stock.
Key words: stainless steel reinforced concrete    bond strength    degradation    corrosion rate    crack width
