摘要
为研究FRP与混凝土的黏结性能对结构加固效果的影响,采用单面剪切的试验方法研究GFRP与混凝土黏接性能.试验考虑的因素包括混凝土表面处理情况、混凝土的强度、GFRP的宽度、GFRP与混凝土宽度比、GFRP片材在混凝土黏结面上的黏结长度等.结果表明:混凝土强度、GFRP宽度以及黏结长度等因素对GFRP与混凝土黏接性能有较大影响.根据试验结果给出建议的GFRP与混凝土黏结强度计算公式.
Strengthening of concrete structures with bonding FRP laminates has been increasingly used in recently years. The effective bond between FRP and concrete substrate is a critical factor that affects strength. Based on the lateral shear experiment, the bond behavior of GFRP and concrete is analyzed. Test variables include surface preparation of concrete, concrete compressive strength, ratio of width for GFRP and concrete, width of GFRP, bond length of GFRP, etc. The results show that concrete strength, the width of GFRP and the bond length of GFRP have a significant influence on the bond behavior between GFRP and concrete. In addition, a suggested formula of bond strength for GFRP and concrete is presented.
