摘要
对碳纤维布加固钢纤维混凝土梁的受弯性能进行了试验研究。试验结果表明,用碳纤维布加固钢纤维混凝土梁可以充分发挥碳纤维布和钢纤维两种材料的性能,使受弯承载力明显提高。根据试验结果和理论分析,提出了一种简化的碳纤维布加固钢纤维混凝土梁的受弯承载力计算方法。经过对比,计算结果与试验结果具有较好的吻合性。
The experimental study on flexural behavior of steel fiber concrete beam strengthening with carbon fiber sheet is presented in this paper. The experimental results show that the strengthening method can make use of the performances of both the carbon fiber sheet and the steel fiber to full advantage. On the basis of that experimental study and theoretical analysis, a simple calculated method for the bearing capacity of steel fiber concrete beam strengthened with carbon fiber sheets is put forward. By comparison, the results of calculation and testing are in good agreement.
