The use of prefabricated concrete systems has greatly contributed to an improvement in construction efficiency; however, connection reliability in structural components remains a major concern. This paper aims to examine the structural performance, bond behavior, and failure modes of half-grouted sleeve connectors (HGSCs) in precast column-footing connections.To achieve this objective, an experimental program involving specimens with varying embedment lengths (4d, 6d, 8d) and grout properties was carried out under axial and cyclic loads. The results of this study were analyzed to examine the load-displacement relationship, bond-slip relationship, and failure modes. Finite Element (FE) simulations using ANSYS code were conducted to validate experimental results.
From this study, it can be deduced that embedment length and grout strength significantly affect connection performance. however, an improvement in grout strength led to an improvement in stiffness but resulted in reduced ductility. This study has ascertained that HGSCs can achieve reliable and ductile performance, making them applicable to seismic and non-seismic regions.
