The frame shear structure consists of two different side force resisting structures, namely a frame and a shear wall structure. The reinforced concrete wallboard is used for replacing beam columns in the frame structure, internal force caused by various loads is controlled, and horizontal force of the structure is controlled. The shear wall structure is mainly divided into a steel frame shear wall structure and a reinforced concrete frame shear wall structure. The structure has high requirements on cement, long calculation and construction process time consumption, and does not have the functions of energy consumption and shock absorption. In addition, the yield sequence of the frame-shear wall structure is shear wall root, each layer of beam end of the frame, each column root of the frame, and the yield and energy consumption capacity of the shear wall greatly influence the bearing capacity and deformation performance of the whole structure. Because the stiffness of the shear wall is much greater than that of the frame, the shear wall takes on most of the shear force, while the frame takes on only a small portion of the shear force. Therefore, under the action of an earthquake, the shear wall usually yields first, then internal force redistribution is generated, and the proportion of shear force borne by the frame is increased. If the seismic action continues to increase, the frame will then also enter a yielding state, causing the building to collapse.
