In this study, the seismic performance of prefabricated bridges connected by grouted sleeves has been evaluated. 12 sleeve specimens and 4 cast-in-place specimens with varying anchorage lengths and water-to-cementitious material ratios were fabricated to investigate the bond-slip performance by uniaxial tension test based on the constitutive relationship of grouted sleeves and bond-slip behaviour between rebar and concrete. A finite element (FE) model was proposed to analyse the prefabricated bridge substructure, considering bond and slip between rebar and sleeve. The corresponding seismic performance under simulated seismic effects was investigated using a multi-angle analysis method. Also, parametric investigation using FE analysis was performed to examine the influence of various parameters on the seismic performance of the specimens. The experiment results showed minimal bonding performance differences between the grouted sleeve specimens and the cast-in-place specimens, indicating that the grouted sleeve connection satisfies the connection performance requirements. The simulation results show that the typical damage form of the prefabricated bridge substructure connected by grouted sleeves is bending, the shape of the hysteresis loop is either shuttle or bow, with the slope of the descending section of the skeleton curve varied not significantly because of the excellent ductility. The results corroborate the excellent seismic performance of prefabricated bridge substructures connected by grouted sleeves.
