摘要: 对变形钢筋与混凝土的黏结性能进行了理论分析,通过对不同锈蚀时间的变形钢筋进行拔出试验,得到变形 钢筋和混凝土的黏结强度与各影响因素之间的关系;根据试验结果及统计分析,给出了变形钢筋锈蚀后与混凝土 的黏结强度计算公式。该结果为钢筋混凝土结构承载能力和耐久性研究打下了基础,可用于桥梁等结构寿命研究。

关键词: 变形钢筋, 锈蚀量, 黏结强度, 变化趋势

Abstract: The adhesion intension between deformed steel bars and concret is analyzed theoretically Th mugh therough the pull-out tests of the deformation of steel bars wilh different corrosion time, the relationships between adhesion and various influen- cing factors are obtained. Based on the test results and ne statistics analysis, the formula of the adhesion intensity between deformed steel bars after corrosion and concrete is given. The test results lay the foundation for the bearing capacity and du- rability research of the concrete structures; at the same time,they can also be used to study the structure life of bridges etc.

Key words: deformed steel bar, corrosion rate, adhesion intension, trend
