CFRP加固石梁的试验研究

Test research on stony beams strengthened by CFRP

对未加固和用碳纤维布加固的石梁的抗弯性能进行了试验研究,分析了未加固石梁与加固石梁在极限承载力和变形能力方面的差异。试验结果表明,碳纤维布加固石梁的承载力和变形能力皆有较大幅度的提高。对未加固石梁和碳纤维布加固石梁的抗弯承载力进行了理论分析,提出了加固后石梁的抗弯承载力实用计算公式,公式计算结果与试验结果吻合较好,可用于指导实际工程的设计。

The experimental study on the flexural behavior of the stony beams and stony beams strengthened by CFRP were carried out. The ultimate bearing capacity and deformation capacity were analyzed. The results show that the flexural capacity and deformation capacity of the strengthened stony beams are greatly improved. Based on the experimental results, the flexural capacity of the stony beams and CFRP strengthened stony beams were analyzed, and the formula of flexural capacity of strengthened stony beams was deduced. Compared with the tests resultS, the formula can be used to guide the design of practical engineering.
