| 摘 要： | 通过三根采用不同纤维(CFRP、C／GFRP和GFRP)正截面加固的混凝土梁和一根对比梁的受弯破坏实验，对比研究了C／GFRP层间混杂形式纤维加固梁的受力特点、破坏形态、合理加固方式、梁体应交情况、承载能力、刚度和变形能力，试验结果表明：采用C／GFRP层间混杂形式纤维加固梁在受弯承载力显著提高的前提下表现出了较好的廷性，这种加固技术切实可行，并可以降低工程造价。

| Abstract: | The flexural behavior of concrete beam strengthened with hybrid C/GFRP is studied. The experimental results present the types of failure, characteristics of strength, reinforced forms, strain of the beams, load-carrying capacity, stiffness, and ductility of three concrete beams strengthened with CFRP, C/GFRP and GFRP contrasted to a concrete beams without FRP reinforcement. Experiment results indicated that the flexural load capability and the ductility of the beams strengthened with hybrid C/GFRP are effectively improved. |
