    Abstract:

    In order to study the bond behavior, anchorage space and reasonable anchorage length of hybrid-bonding of FRP, the destructive tests of 17 experiment beams which with mid-span pre-cutting fissures have been done. Compared with EB-FRP system, it is found that HB-FRP system is improved a lot in ductility, bearing capacity, FRP’s peeling stress and so on. The formulas for calculating HB-FRP and EB-FRP’s induced peeling strength by middle crack and a more reasonable estimation formula for anchorage space are presented based on the experimental data and theoretical analysis. Calculating results are coincided with experimental results, which can serve as a reference for further researches and engineering applications.
