| 摘 要： | 纤维增强复合材料板与混凝土的有效粘结是保证FRP-混凝土组合结构正常工作的基础.采用FRP板-混凝土块搭接接头的单剪试验方法研究FRP板与混凝土的粘结性能,为增强粘结效果,对FRP板表面采取了粘结粗砂的措施,试验同时考虑粘砂长度对粘结性能的影响.试验结果表明:(1)粘结破坏为典型的脆性破坏;(2)平均粘结强度与粘砂长度近似成反比;(3)粘结粗砂法可作为FRP-混凝土组合结构中有效的组合界面连接措施.提出的抗剪设计方法可用于FRP-混凝土组合结构中组合界面抗剪设计.

| Abstract: | Effective bond between Fiber Reinforced Polymer(FRP) plate and concrete is the base of ensuring composite behavior of hybrid FRP-concrete structures.The bond behavior between FRP plate and concrete is studied by experiment on a single shear test setup.Coarse sand coating method for the surface of FRP plate is applied to strengthen the bond behavior between the two materials.Various lengths of coarse sand coating are also considered in this test.Following conclusions are drawn from this study:(1) the failure mode of all specimens is typical brittle failure;(2) average bond strengths between FRP plate and concrete are in inverse proportion to the lengths of coarse sand coating;(3) coarse sand coating is considered as an effective bond measure for the interface between FRP and concrete in hybrid FRP-concrete structures;(4) the proposed design methods can be used for shear design of the interface between FRP plate and concrete in hybrid FRPconcrete structures. |
