5 specimens of prefabricated pile combined with pile caps are tested under low cycle reciprocating loading. The failure patterns, the bearing capacity and the ductility, the forces in anchoring reinforcing bars, as well as the influence of different forms of the precast pile and pile cap anchoring reinforcing bars on the mechanical properties of the specimen are studied. It is shown that by anchoring reinforced connecting plate welded specimens, the inclined anchoring reinforcing bars can play a role in delaying the growth of cracks, increasing the bearing capacity of the specimen. The specimens with the pile body and the anchoring reinforcing bars can significantly improve the integrity of the pile cap assembly of the specimen and increase the bearing capacity, the ductility, and the deformation ability, and the bearing capacity of the anchoring reinforcing bars of oblique angle is better than that of the rectangular specimens.
