The invention relates to a double core pre-stretch self-resetting energy dissipation diagonal brace damping device which combines high elongation and anti-frustration.

At this stage of the seismic design, in addition to the need for sufficient allowable strength, it is desirable to have good toughness for more economical and safer purposes. In the case of structural systems that are dissipated to dissipate energy, they are usually subjected to seismic energy, and permanent stresses cause residual stress in the building, posing a potential hazard and requiring future maintenance to solve the problem. At present, the common support system is mainly based on the structural member to fall or frustration, but under the repeated load, the deformation caused by the fall or the setback will affect the safety of the building structure and the difficulty in rescue. degree. The self-resetting system and the structural system based on the energy dissipation of the friction plate have been replaced, and the problem of residual stress due to structural deformation has been solved.

U.S. Patent No. 2012/0000147 discloses a dual core pre-stretch self-resetting self-resetting energy dissipating support device. The device comprises a first core member composed of one steel, a second core member which is covered by the first core member and is also composed of a square steel, two inner bottom plates disposed at two ends of the second core member, and a Covering the first core component and also by the square steel group An outer layer member, two outer layer bottom plates disposed at both ends of the outer layer member, and two sets of pre-stretch tensile members. One set of pre-tensioned tensile members has one end anchored to one of the inner bottom plates, the other end of which is anchored to the opposite outer bottom plate; the other set of pre-tensioned tensile members are anchored to the other inner bottom plate With another outer bottom plate. The surface of the first core member is further provided with a friction energy dissipation plate, and the outer layer member is provided with angle steel, and the friction energy dissipation plate is locked with the angle steel by bolts, and when the first core member and the outer layer member are relatively displaced, friction is used to eliminate can.

In terms of mechanical reaction, when the device is pressed, external force is transmitted from the building to the first core member and one of the outer bottom plates, and the outer bottom plate transmits the force to the opposite inner bottom plate through a set of pre-stretched tensile members connected thereto. The inner bottom plate then transmits the force to the opposite inner bottom plate via the second core member, and the inner bottom plate transfers the force to the opposite outer bottom plate via another set of pre-stretch tensile members, and the outer bottom plate finally passes the outer layer member Send power out. During the stress process, the first core member, the second core member and the outer layer member are all relatively displaced, and the friction energy dissipation plate, the angle steel, and the bolt are used for energy dissipation during displacement. In addition, the two sets of pre-stretched tensile members each have an elongation of δ, so that the relative displacement of the first core member and the outer layer member can reach an elongation of 2δ, so that the total elongation can reach twice the deformation of the conventional device without Will destroy.

Under the earthquake, the device uses the restoring force of the pre-force to eliminate the residual stress of the deformation of the structure. However, the more the number of repeated loadings during the earthquake, the more obvious the wear of the energy dissipating components (friction energy dissipating plates, angle steels, and bolts). The loss of these components will reduce the energy dissipation efficiency and require frequent replacement and repair. .
