Connect the assembled self-resetting controllable hinged energy-dissipating shear wall described in the utility model with the building. Since the shear wall described in the utility model has push-pull symmetry, no matter it is under tension or under compression In this case, the stress state of the shear wall is always consistent, as shown in Figure 10, the hysteresis curve of the system is completely symmetrical on the left and right;

The components of the whole frame system can be replaced, and the whole friction wall system has 4 safety lines of defense: the hinge frame reset system is the first line of defense, mainly provided by the arch spring to provide the reset force, and the hinge frame provides the structure with lateral stiffness; the friction wall and the shear The friction force between the force walls is the second line of defense, which mainly provides the structure with lateral stiffness and friction energy dissipation; once the friction surface of the shear wall and the friction wall is damaged, the friction wall has a certain horizontal bearing capacity and can continue to provide the structure with For horizontal shear force, the friction wall is the third line of defense of the structure; once the friction wall is damaged, the shear wall is equivalent to an ordinary shear wall, which can bear both horizontal shear force and vertical self-weight, and the shear wall is the last structure of the structure. A defense line; according to the damage sequence of the 4 defense lines, the damage of the arched spring, the damage of the viscous damping surface of the friction wall and the shear wall, the damage of the friction wall and the damage of the shear wall; according to the design goal of the shear system, the structural The maximum layer damage only reaches the second layer;

Replaceability of the entire frame system components. After the structural arch spring is damaged, the friction surface is not sure to be damaged. Therefore, the arch spring should be replaced first. When replacing the arch spring, only one side of the node must be replaced each time. On both sides, because there is no support on one side of the node, the side of the column becomes hinged, and the force carried by one side of the column is transmitted to other components, causing unnecessary danger; when replacing the arch spring, replace the bottom of the column first, in order to further stabilize the structure , and then replace the column top; after the arch spring is replaced, the friction wall can be disassembled for inspection, and the viscous layer can be repaired.
