摘要

摘要: 预制楼板连接件细部构造对其抗剪性能的影响较大，但是目前对连接件细部构造的规定不够明确。以发卡式连接件的埋置深度、嵌条长度、锚板厚度及其挑出长度为参数，通过对其进行平面内剪切荷载作用下的数值模拟分析，研究连接件细部构造对发卡式连接件抗剪承载力、刚度和变形能力等方面的影响。在分析的基础上提出了发卡式连接件的细部构造建议，为发卡式连接件的设计和施工提供参考。

Abstract: The detailed formations of precast floor slab connectors have significant effect on its shear capacity, but there is no such specific provision on it at present.The effects of detailed formations on the shear strength, stiffness and deformation capacity of hairpin connectors(HPC) are studied, through numerical simulation analysis of it under in-plane shear force.The imbedded depth(d), slug length(h), steel plate thickness(t)and its stickout(s)are taken as parameters.On the basis of analysis, the recommendations on formation details of HPC are proposed for design and construction.
