Abstract: Using rocking components to control the deformation mode of frame structures can effectively improve their seismic performance. In order to further study the mechanical behavior and deformation mechanism of the frame-rocking wall, a bending beam-shear lumped-mass model is established. The equivalent single degree of freedom motion equation is derived according to the lateral displacement of the top floor. Considering the non-uniform distribution of story stiffness, the numerical iteration algorithm is used to achieve deformation compatibility between the frame and the rocking wall, and a seismic response spectrum analysis model is established. Considering the elastic-plastic mechanical behavior of the story, the structural base shear force is calculated based on the top displacement, and a push-over analysis model is established,adaptive lateral force mode is achieved. A ten-story (rocking wall) frame is taken as an example, compared with the finite element analysis result, the rationality of the analysis model is verified. The influence of the rocking wall bending stiffness and the distribution of frame stiffness on the structural seismic response is discussed, and its seismic performance is evaluated. The deformation and internal force evolution law of the structure during the entire process of push-over are analyzed. Research reveals that the analysis models established based on the bending beam shear lumped-mass model can reasonably reflect the frame-rocking wall structure's internal force distribution and deformation evolution. Reasonably designing the frame stiffness distribution can reduce the stiffness and internal force demand of the rocking wall. The non-uniformity of deformation decreases with the development of frame plasticity, but the internal force demand of the rocking wall increases accordingly. Within the scope of this research, the position of the shear control section of the rocking wall is consistent with that of the frame maximum story drift, and the bending moment control section is generated at the maximum lateral stiffness position at the bottom of the frame.
