采用碳纤维布施加预应力后加固混凝土梁,可以充分发挥碳纤维材料的高强度特点,显著减小梁的裂缝和挠度,提高加固效率。对预应力CFRP布加固钢筋混凝土T形梁的各种破坏模式、界限和理论计算进行了较系统的分析和总结,并给出了判别破坏模式的方法和计算预应力碳纤维布加固混凝土T形梁正截面的计算公式,计算出的结果与试验结果较吻合。
The use of carbon fiber reinforced plastic prestressed reinforced concrete beams, carbon fiber materials can give full play to the characteristics of high strength, significantly reduce the beam cracks and deflection, improve the reinforcement efficiency. The various failure modes, boundary and theoretical calculation of prestressed CFRP sheet reinforced concrete T-beams are systematically analyzed and summarized, and the method of determining failure modes and the calculation of prestressed carbon fiber reinforced concrete T-beams The calculation formula of the normal section and the calculated result are in good agreement with the test results.
