摘 要:碳纤维布具有轻质、高强、耐久性好等特性,预应力碳纤维布加固技术已成为一种新型建筑加固技术。在试验基础上,对预应力碳纤维加固钢筋混凝土梁的受力性能进行了分析,提出了预应力碳纤维布加固钢筋混凝土梁的抗弯正截面承载力的计算公式,计算公式与试验结果较为接近,试验值略高于理论值,说明理论计算有一定的安全储备,较为保守安全。
Abstract: Because of having light weight, high strength, good durability and other characteristics, prestressed CFRP reinforcement technology has become a new kind of reinforcement technology. Base on the test, the mechanical properties of prestressed CFRP concrete beams are analyzed. The calculation formula for normal section flexural capacity of the prestressed CFRP concrete beams is put forward. The test results are generally slightly higher than the results got by the calculation formula, which shows that the theory calculation values are conservative and have the security of reserves.
