FRP胶栓混接节点兼具胶接节点和栓接节点的优点，静力性能优良，但疲劳破坏机理尚不明确；为了深入研究FRP胶栓混接节点在多种工况下的疲劳性能，文中设计制作了单搭接FRP胶栓混接节点试件。首先进行轴向拉伸及四边剪切作用下的静载试验，得到了相应的破坏模态和极限承载力；随后开展两种工况下的高周疲劳荷载试验，采用声发射技术测得了胶层的疲劳损伤发展过程，得到了试件的疲劳破坏模式、特征疲劳寿命以及刚度退化规律，并提出了疲劳寿命预测方法建议。结果表明：FRP胶栓混接节点的抗疲劳性能主要由栓接控制，其疲劳破坏过程可分为胶层累积损伤、胶层破坏、FRP累积损伤、FRP破坏4个阶段，其中胶层破坏阶段和FRP破坏阶段的声发射特征参数发生显著变化，可作为识别破坏发生的依据；当螺栓数量较少时两种工况下的试件均发生螺帽挤入FRP板的破坏，当螺栓数量较多时拉伸试件以FRP板孔边拉剪破坏为主，剪切试件以FRP板整体剪切破坏为主；螺栓数量增加能够显著提升拉伸试件的特征疲劳寿命，并有效抑制疲劳破坏过程中的刚度下降速度，但剪切试件的疲劳性能对螺栓数量不敏感；基于试验数据拟合得到的不同工况下的S-N曲线公式可为FRP胶栓混接节点疲劳寿命计算提供参考，有助于此类节点在桥梁等主要承受反复荷载作用结构中的应用。

FRP adhesive & bolted hybrid joint has the combined advantages of adhesive joints and bolted joints, which behave enhanced static performance, but its fatigue failure mechanism still needs to be studied. In order to study the fatigue performance of hybrid FRP joints under various working conditions, this study designed and manufactured single-lap hybrid FRP joints specimens. Firstly, the static load tests under axial tension loads and four side shear loads were carried out, and the corresponding failure modes and ultimate bearing capacity were obtained. Then, high cycle fatigue tests under two working conditions were carried out, and the damage process of the adhesive layer was measured by acoustic emission (AE) technology. The fatigue failure mode, characteristic fatigue life and stiffness degradation of the specimen were obtained, and the fatigue life prediction method was proposed. The results indicate that the anti- -fatigue performance of hybrid FRP joints is mainly controlled by bolted-connection, and its fatigue failure process can be divided into four stages: adhesive layer cumulative damage, adhesive layer failure, FRP cumulative damage, and FRP failure. Among them, the AE characteristic parameters of adhesive layer failure stage and FRP failure stage change significantly, and this can be used as the basis for identifying the failure occurrence. When the number of bolts is small, two working condition show the similar failure mode of the nut squeezing into the FRP plate. When the number of bolts is large, for tensile specimens, the tensile-shear failure mainly occurs at the hole of the FRP plate; for shear specimens, the failure mode is overall shear failure of FRP plate. The increase of the number of bolts can significantly improve the characteristic fatigue life of tensile specimens, and effectively inhibit the stiffness degradation during fatigue loads, but the improvement of fatigue performance of shear specimens is not obvious with the increasing number of bolts. The S-N curve of two working conditions obtained based on the test data can provide a reference for the fatigue life calculation of hybrid FRP joints, and help the application of such joints in bridges and other structures that mainly bear repeated loads.
