摘要
预应力碳纤维布具有轻便、高模量、耐久性好的特点,对预应力碳纤维布加固钢筋混凝土梁的抗弯性能进行了研究.将4根长度为1.8 m的钢筋混凝土梁在不同预应力水平下的加固性能进行了试验,并对试验结果进行了分析.结果表明,预应力碳纤维布加固构件对提高梁的抗弯承载力和改善截面刚度是有效的.
Strengthening beams technology with prestressed CFRP sheets has the advantages of light mass,high modulus,good durability.Flexural strengthening reinforced concrete beams with prestressed CFRP sheets is mainly researched.And four strengthened beams,whose length is 1.8 meter,are tested in different prestressed forces.and the experimental results are analyzed.The analytic results show that,this method that reinforces beams with carbon fiber reinforced plolymer is valid to raise the flexural load-bearing capac...
