摘要:

Socket connection is commonly used for connections between precast components, which has the advantages of good integrity and high construction fault tolerance. To further investigate the bond -slip behavior and improve the engineering design of Ultra High -Performance Concrete (UHPC)-filled concrete -filled steel tube (CFST) column -beam socket connections, this paper conducted bond -slip experiments on UHPC-filled CFST socket connections (UCSC) with different parameters (socket depth, presence of studs) to reveal their bond -slip properties. In addition, to conduct further parametric analysis, a reliable finite element model (FEM) of the UCSC joint was developed. Based on the experimental data and finite element analysis (FEA) results, a simplified calculation equation and a normalized bond -slip relationship model was established to estimate the bond -slip performance of UCSC. The research results suggested that the bond -slip behavior of the UCSC was sensitive to the socket depth, the presence of studs and the diameter of CFST. The FEM is capable of estimating the forcedisplacement relationship and the damage distribution of the UCSC joint under vertical loads. The developed simplified equation and normalized bond -slip relationship have been validated, and can be employed to predict the ultimate bonding bearing capacity and the bond -slip relation of UCSC joints, respectively. Finally, design recommendations were proposed for the engineering design of UCSC. The UCSC method is required to ensure a socket depth at least 1.0 D and a certain number of shear studs to connect the column -beam joint.
