碳纤维布加固钢筋混凝土枕木梁承载力研究

Research on loading capacity of carbon fiber cloth consolidated and reinforced concrete sleeper beam

初步研究了采用碳纤维布材料加固钢筋混凝土枕木梁后抗弯承载力提高幅度,考虑施工技术、实际环境,以4片钢筋混凝土枕木梁试验为依据,研究碳纤维布对钢筋混凝土构件抗弯承载力的影响规律,试验结果表明在粘贴碳纤维布的情况下能对钢筋混凝土抗弯承载力提高25%左右,为深入研究打下了基础。

The study has the primary research on the promotion of the flexural capacity by adopting the carbon fiber cloth consolidated and reinforced concrete sleeper beam,considers the construction technique and the factual environment,researches the influence law of the carbon fiber on the flexural capacity of the reinforced concrete components by referring to the four reinforced concrete sleeper beam experiments,and proves by the experiment result that the flexural capacity of the reinforced concrete can be improved about 25% by being affixed with the carbon fiber cloth,so as to lay the foundation for the deeper research.
