摘　　要：文中设计并制作了六个不同的GFRP开孔板连接件,通过单调加载拔出试验分析了GFRP开孔板连接件的破坏模式、荷载-滑移曲线,探讨了开孔直径、开孔数量参数对GFRP开孔板连接件抗剪性能的影响,并回归拟合出了简化的荷载-滑移表达式.结果表明:增大开孔直径和增加开孔数量可以提高GFRP开孔板连接件的抗剪承载力;建立的简化荷载-滑移模型与试验结果吻合较好.Six different GFRP perforated plate connectors were designed and manufactured,and the failure mode and load-slip curve of GFRP perforated plate connectors were analyzed by monotonic loading pull-out test.The influence of the parameters of hole diameter and hole number on the shear performance of GFRP perforated plate connectors was discussed,and a simplified load-slip expression was fitted by regression.The results show that increasing the diameter and number of holes can improve the shear capacity of GFRP perforated plate connectors.The simplified load-slip model is in good agreement with the experimental results.
