| 摘 要： | FRP-混凝土组合板界面的可靠连接是保证其正常工作的基础。为考察组合板中的界面粘结性能，该文对采取4种连接方式的27个玻璃FRP（GFRP）-混凝土组合构件进行双剪推出试验，根据试验结果分析构件的破坏模式、承载力变化及界面滑移情况。研究结果表明：4种连接方式均获得了较高的粘结强度，可考虑作为GFRP-混凝土组合板的界面抗剪构造措施；GFRP-混凝土界面粘结强度与混凝土强度等级、界面粗糙程度、胶结剂的粘结能力、剪力键布置方式有关，且随混凝土强度等级的提高而有所增大。基于该文的试验设计和试验结果，对试验中的3个试件进行了三维非线性有限元分析。

| Abstract: | The reliable interface connection is important to secure the composite action of the FRP (Fibre Reinforced Polymer)-concrete composite deck in normal operation. In order to investigate the bonding behavior of the interface of the glass FRP (GFRP)-concrete composite deck, 27 GFRP-concrete composite desk connection specimens with four different kinds of bonding patterns were tested by using the double shear experiments in this paper. The failure mode, bearing capacity, and interface slip were analyzed based on the experimental results. The experimental results show that these four kinds of bonding patterns have improved the bonding behavior and can be potentially used as the shear resistance countermeasures. The bonding strength of the interface of the GFRP-concrete composite deck is related to the surface roughness condition, bonding behavior of cohesive, arrangement pattern of the shear connectors, and concrete strength. Finite element analysis has been conducted on three specimens and compared with experimental results. |
