| 摘 要： | PBL剪力连接件是一种新型的剪力连接件,具有承载力高、延性好和抗疲劳性能强的优点。进行了1组PBL剪力连接件的试验研究,验证了有限元分析模型的可靠性。通过进行4组共13个不同的PBL试件有限元分析,结果表明：混凝土的强度和加贯通钢筋对其承载力的影响最为明显,钢板的厚度和钢板孔径的大小对其承载力影响不明显。

| Abstract: | The PBL shear connector is a new type of shear connectors with the advantages of high bearing capacity,good ductility and strong fatigue resistance.A group of PBL shear connectors are tested to testify the reliability of the finite element analysis model.Through the finite element analysis of four different groups of PBL samples,altogether 13 samples,it is found thatthe effect of the strength of concrete and the perforated reinforcement on its bearing capacity is the obvious,while that of the thickness of plates and the size of the plate aperture on its bearing capacity is not obvious. |
