摘要
首次提出用玻璃纤维布和碳纤维布对钢筋混凝土梁进行复合加固的思路。通过对比试验研究 ,证实相对碳纤维加固方法而言 ,复合纤维加固法既能提高构件的塑性 ,又能显著降低加固成本。
A concept and method aimed at strengthening concrete beams with both CFRP and GFRP was proposed for the first time.Comparing test was performed.Test results showed that,compared with the CFRP strengthening method,the strengthening concrete beams with both CFRP and GFRP can not only heighten plasticity but also obtain the economical effect.
