In order to calculate the bearing capacity of steel beam assembly joints and improve the stiffness of assembly joints, this paper studies the seismic performance of fibre-reinforced high-strength concrete steel beam assembly joints. Firstly, design fibre reinforced high-strength concrete steel beam assembly node specimens. Then, construct a constitutive model of concrete steel beams and determine the equilibrium conditions of the upper half of the nodes. Finally, the bending moments on both sides of the node area are obtained through beam end sensors, and the shear bearing capacity of the assembly node is calculated to achieve seismic performance research of the node. The results show that under the method proposed in this paper, the degradation of node strength is relatively small, stable between 0.97 and 1.10, and the bearing capacity can reach 905.22 kN, indicating that the method proposed in this paper can effectively improve the seismic performance of nodes.
