The static and quasi-static behaviors of cast-in-place pier and grouted sleeve connected precast pier are simulated by ABAQUS, which are based on the steel hysteretic constitutive model. The accuracy of the finite element simulation is verified by comparing with the existing experimental results. Then the simulation results of the two types of piers are compared and analyzed. The results show that: the seismic performance of precast pier connected with grouting sleeve is similar to that of cast-in-place pier, they both have good plastic deformation capacity. When the displacement is large, grouting sleeve connected pier has higher hysteretic energy dissipation than that of cast-in-place pier, it’s suitable in high earthquake region; The steel hysteretic model can better simulate the seismic performance of reinforced concrete structure under cycle load.
