| 摘 要： | 对现有典型钢筋锈蚀模型进行了比较分析,选择考虑因素较全面合理的Youping Liu指数模型作为钢筋锈蚀基本模型。将考虑荷载影响的氯离子扩散模型引入钢筋锈蚀基本模型中,建立了考虑荷载影响的钢筋混凝土构件钢筋锈蚀模型。通过实例计算,分析了钢筋锈蚀速度随时间的变化规律。

| Abstract: | The study and comparison on the representative corrosion models of reinforcing bar were conducted and the Youping Liu＇s corrosion model was selected as the basic corrosion model.The reinforcing bar corrosion model of RC member considering load effect was presented by introducing the chloride diffusion model considering loading effect into the Youping Liu＇s corrosion model of reinforcing bar.The variations of reinforcing bar corrosion with time were shown by an example. |
