碳纤维加固钢筋混凝土梁抗弯性能试验研究

Experimental research of RC beams strengyhened by carbon fiber reinforced plastic

通过４根用碳纤维补强钢筋混凝土梁的试验，主要研究碳纤维布对钢筋混凝土梁抗弯性能的影响和作用。实验表明，粘贴碳纤维布后，试验梁的抗弯承载力明显提高，但对梁的刚度和变形性能影响较小，同时用计算机程序进行理论分析，试验数据与理论分析较好吻合。

Four simply supported beams strengthened with carbon fiber reinforced plastic(CFRP) are tested. experimental results indicated the CFRP can evidently in- crease the bending capacity of RC bearns. but the effect on the stiffness of beams strengthened is rather small. While a computer analysis program is developed, theoreti- cal method have been well conform to the experimental re- sults.
