摘要
混凝土结构表层嵌贴碳纤维(CFRP)板或筋,是一种新兴的结构加固方法。本文对2根对比梁和5根表层嵌贴CFRP板条的抗剪加固梁进行了试验研究,考虑了CFRP板间距、CFRP板加固量和箍筋配筋率三个参数对抗剪承载力的影响。研究表明,表层嵌贴CFRP板加固法能有效提高钢筋混凝土有腹筋梁的抗剪承载力。文中还对加固梁的破坏模式作了分析。
The use of near-surface mounted （NSM） CFRP is an emerging technology for structural strengthening. Experimental research on the shear behavior of 2 RC beams and 5 RC beams strengthened by NSM CFRP strips has been carried out,and three factors are taken into account： spacing of CFRP strips, amount of CFRP and spacing of stirrups. The research indicates that the shear strength of the strengthened RC beams is increased efficiently. The failure modes are also discussed in this paper.
