摘要
因为弹性模量和施工工艺等问题,FRP和混凝土界面本身的抗剪能力很小,界面连接方式往往成为控制整体结构强度的关键因素。故从理论和试验方面介绍十几年来FRP-混凝土组合梁界面抗剪连接的研究成果,总结和分析几种界面连接形式的优缺点,并对组合梁的界面抗剪问题提出一些展望和建议。可为FRP-混凝土组合结构在实际工程应用中的界面连接设计提供参考。
Because of the elastic modulus and the construction craft, the shear capacity is small between the interface of FRP and concrete, so the interface connection could be the key factors to control the strength of the whole structure. This paper introduces the research results of interface shear connection between FRP and concrete in ten years. The author summarizes and analysis the advantages and disadvantages of several interface connection methods, then the author puts forward some suggestions on the interface shear resistance of composite beams. This paper can provide reference for the interface connection design of FRP- concrete composite structure in practical engineering application.
