| 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。

| Abstract: | The adhesion intension between deformed steel bars and concrete is analyzed theoretically.Through the pull-out tests of the deformation of steel bars with different corrosion time,the relationships between adhesion and various influencing factors are obtained.Based on the test results and the 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 durability research of the co... |
