Abstract: In order to study the hysteretic performance of RC prefabricated bolted beam-column joint,low-cyclic loading test was carried out at the beam end of this joint. Then the finite element analysis software ABAQUS is used to establish the three-dimensional finite element model of the joint followed with data analyzing. It is found that the data analysis results are in good agreement with the test results. On this basis,the test specimens are analyzed with variable parameters,and the seismic performance of the test specimens is analyzed by changing the bolt strength and the column concrete strength in the finite element model. The results show that the joint present good seismic performance in experiments and numerical simulations, which meet the seismic code requirements of strong column and weak beam. The increase of bolt strength can effectively improve the bearing capacity and energy dissipation capacity. Under the same loading system,the enhancement of column concrete strength has little effect on the hysteretic performance of the joint. With the same concrete strength of the beam and column, both hysteretic curves of the joints are full which behave great seismic performance.
