The corrosion of longitudinal bars in the midspan increases the width of diagonal cracks under service loads.4. 梁跨内的纵筋锈蚀使梁在使用荷载下的斜裂缝宽度增大。
The relationship between the steel corrosion ratio and parameters in the predeterminate model is also discussed in the paper, and some useful results are obtained. 另外,在同一混凝土构件中,箍筋锈蚀程度要比纵筋更为严重,这就要求我们重视混凝土结构的抗剪耐久性的失效问题。
