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 flexural performance of steel fiber reinforced concrete beams strengthened with carbon fiber sheets was experimentally studied. The test results show that the use of carbon fiber reinforced steel fiber reinforced concrete beams can give full play to the performance of carbon fiber cloth and steel fiber materials, so that the flexural bearing capacity is significantly improved. Based on the experimental results and theoretical analysis, a simplified calculation method for the flexural bearing capacity of steel fiber reinforced concrete beams reinforced with carbon fiber sheets was proposed. After comparison, the calculated results are in good agreement with the test results.
