摘　　要：针对混凝土结构容易发生脆性剪切破坏这一特点,通过对8根CFRP-PCPs复合筋嵌贴加固的钢筋混凝土梁的抗剪试验,主要研究CFRP-PCPs复合筋棱柱体对钢筋混凝土梁的抗剪作用和影响,考查了嵌贴加固间距、嵌贴加固方向、复合筋张拉控制应力以及不同复合筋材质对嵌贴加固效果的影响。试验结果表明,CFRP-PCPs复合筋棱柱体对钢筋混凝土梁的抗剪性能有明显的提高。For this characteristic concrete structures are prone to brittle shear failure, it through to 8 CFRP-PCPs composite tendons em- bedded on reinforcement of reinforced concrete beam shear test, which main research the shear effect and influence of reinforced concrete beam reinforced by CFRP-PCPs composite tendons, examining the embedded post reinforcement spacing, embedded direction, compound muscle tension control stress, and different composite reinforcement material for the embedded reinforcement effect.The test results show that the composite reinforced CFRP-PCPs prism on the shear properties of reinforced concrete beam significantly improved.
