The stiffness ratio determines the distribution of internal force in structural members and the strength ratio influences the failure process and final failure degree of structural members. Based on the assumption that the floor and frame structure are all working together, the paper establishes an example of plane frame, which includes 6 different linear stiffness ratios and 3 different bending capacity ratios between the beam and column. The influence of linear stiffness ratio and bending strength ratio on seismic performance and failure mode of frame structure is investigated by ABAQUS nonlinear analysis. The research shows that the accurate analysis of the seismic performance of the structure is based on accurate consideration of cooperative working degree of the floor and structure under horizontal earthquake. To ensure that the structure appears more reasonable "beam column mixed hinge" failure mode, the stiffness and strength matching should be reasonable. The actual bending strength ratio of the column and beam should be more than 1.1 when the linear stiffness ratio of the beam and column is 1~4; the actual bending strength ratio of the column and beam should be more than 1.3 when the linear stiffness ratio of the beam and the column is less than 1 or more than 4.
