摘　　要：很多研究都证明FRP与砖之间存在一个有效粘结长度,当实际的FRP粘结长度大于此长度时,极限承载力就不再增加了。通过对收集到的试验数据进行分析,研究FRP粘结层数、FRP种类以及砖强度对FRP-砖有效粘结长度的影响。结果表明:影响FRP-砖有效粘结长度的因素主要是FRP种类和FRP粘结层数,但是随着粘结层数的增加,其有效粘结长度并不呈线性增长。基于对试验数据的分析,提出了FRP-砖有效粘结长度计算公式,计算值与试验值能够较好吻合。Numerous studies have proved that there is an effective bond length between FRP and brick. When the actual bond length of FRP is greater than the length, the ultimate bearing capacity is no longer increased. Through analysis of the collected test data, the influence of bond layers,types of FRP and brick compressive strength on the effective bond length of FRP-brick are investigated. The results showed that the main factors influencing the effective bond length of FRP-brick is bond layers, types of FRP, but the effective bond length is not in direct proportion to the the bond layer. Based on the analysis of test data, formulas for calculating the effective bond length between FRP and brick are proposed and good correlation are observed between calculated and measured results.
