摘要

摘要: 为了应对组合空腹夹层板材料交界面处的复杂应力状态,提高结构组合作用性能,提出一种附加钢管的PBL剪力键,并对其开展了试验分析与有限元模拟研究。分别对附加钢管的PBL剪力键试件与传统PBL剪力键试件进行推出试验,通过分析两组试件的破坏现象、荷载-滑移曲线和抗剪刚度等指标,验证了附加钢管对PBL剪力键的抗剪性能具有显著的提高作用。通过有限元参数扩展分析进一步揭示了该类PBL剪力键各构件应力分布状态以及附加钢管参数对该新型PBL剪力键抗剪刚度的影响,发现附加钢管的存在避免了内部构件过早出现应力集中现象,保护了内部构件。研究表明:钢管直径、钢管壁厚以及钢管长度等钢管参数对该类剪力键的承载性能均具有不同程度的影响,其中钢管直径的影响最为显著。

Abstract: In order to cope with the complicated stress state at the material interface of the composite open-web sandwich plate and to improve the performance of the combined action of the structure, the paper proposed a PBL shear connectors with additional steel pipes and carried out experimental analyses and finite element simulation studies on it. The push-out tests of PBL shear connectors specimens with additional steel pipes and traditional PBL shear connectors specimens were carried out respectively. By analyzing the failure phenomenon, load-slip curves and shear stiffness of the two groups of specimens, it was found that the additional steel pipes can significantly improve the shear performance of PBL shear connectors. The stress distribution of each member of this type of PBL shear connectors and the influence of additional steel pipe parameters on the shear stiffness of this new type of PBL shear connectors were further revealed through the finite element parameter expansion analysis. It was found that the existence of additional steel pipe could avoid the phenomenon of stress concentration in the internal component and protect the internal component. The study showed that steel pipe parameters such as pipe diameter, pipe wall thickness and pipe length had different degrees of influence on the bearing capacity of this type of shear connector, with the most significant effect of pipe diameter.
