摘要
探讨在原有抗弯能力不足的空心板下采用粘贴碳纤维加固的方法,对加固前后的荷载进行对比试验,结果表明,粘贴碳纤维可以有效增大截面抗弯刚度,改善梁底砼应变水平。
The design means of carbon fiber reinforcement are discussed in the paper. Hollow slabs lacking in capability of bending resistance were bonded externally with CF, and the contrastive test was made. The experimental results indicated that strengthening with CF can not only enhance the stiffness of sectional bending resistance, but also reduce the strain level in the bottom of beam.
