Working principle:

the assembled self-resetting controllable hinging energy-consuming shear wall is connected with a building, and the shear wall has push-pull symmetry, so that the stress state of the shear wall is consistent all the time no matter in a tensile state or a compression state, as the hysteresis curve of the system of figure 10 is completely symmetrical left and right;

the whole frame system component is replaceable, and the whole friction wall system has 4 safety defense lines: the hinge frame resetting system is a first defense line, resetting force is mainly provided by an arch spring, and the hinge frame provides lateral rigidity for the structure; the friction force between the friction wall and the shear wall is a second defense line, and mainly provides side rigidity resistance and friction energy consumption for the structure; once the friction surface layers of the shear wall and the friction wall are damaged, the friction wall has a certain horizontal bearing capacity and can continuously provide horizontal shear force for the structure, and the friction wall is a third defense line for the structure; once the friction wall is broken, the shear wall is equivalent to a common shear wall, namely, the shear wall can bear vertical dead weight at horizontal shear force, and the shear wall is the last defense line of the structure; the damage sequence of the 4-fold defense line is arch spring damage, viscous damping surface damage on the friction wall and the shear wall, friction wall damage and shear wall damage; according to the design target of the shear system, the maximum level damage of the structure only reaches the second layer;

the structural arch spring is damaged, the friction surface is still indeterminate and damaged, so that the arch spring is replaced firstly, only one side of a node needs to be replaced each time when the arch spring is replaced, and meanwhile, when two sides are replaced, one side of the node is not supported, one side of a column is hinged, and the force borne by one side of the column is transferred to other components, so that unnecessary danger is caused; when the arch spring is replaced, the column bottom is replaced firstly, and then the column top is replaced in order to further stabilize the structure; after the arch spring is replaced, the friction wall can be detached for inspection, and the viscous layer can be repaired.
