Double core pre-stretch self-resetting energy-saving support device

The present invention relates to an energy dissipating support device, and more particularly to a dual core pre-stretch self-resetting energy dissipating support device for increasing the amount of stretch.

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, residual permanent deformation is usually caused after large deformation, causing 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 research and application of energy dissipation support based on frustration behavior and friction behavior have achieved concrete results in many aspects. However, these two energy dissipation behaviors have no self-resetting function and cannot solve residual deformation. The problem. Therefore, the current self-resetting system is the main development direction, and the self-resetting method is implemented by a reliable spring or a pre-force method.

U.S. Patent No. 5,819,414 discloses a device for applying pressure in a bundled manner, such that the overall behavior of the device is similar to that of a spring and has a self-resetting function, and the energy is dissipated by the contact friction of the intermediate member.

Referring to Figures 1 through 7, U.S. Patent Publication No. 2008/0016794 discloses a device for providing a self-resetting function in a tensile preload. For convenience of explanation, FIGS. 1 through 7 re-assign component numbers. Figure 1 is a side cross-sectional view of the apparatus, and Figure 2 is a cross-sectional view of section 1-1. The device comprises an inner core member 11 composed of one type of steel, an inner bottom plate 12 fixed to the first end of the inner core member 11, and a set of outer layer members 13 which are covered by the inner core member 11 and which are also composed of square steel. The outer bottom plates 15 and 16 fixed to both ends of the outer layer member 13, and the anchor device 21 and the pre-force member 22. The inner core member 11 also has an extension section 111 for engaging the beam and column in the building frame; the outer layer member 13 has two extensions 131 for joining the beams and columns in the building frame. The energy dissipating plate 112 in the inner core member 11, the frictional energy dissipating plate 132 of the outer layer member 13, and the angle steel 133 are combined by bolts 14, and the relative displacement of the inner core member 11 and the outer layer member 13 is dissipated by friction.

For mechanical reactions, please refer to Figure 3 to Figure 5. When the device is not subjected to external forces, the mechanical behavior is shown in Figure 3. When the device is pressed, the inner core member 11, the inner bottom plate 12 and the outer layer member 13 are the pressure members in the device, and the external force is transmitted from the both end extensions 131 of the outer member 13 to the opposite outer bottom plate as shown in FIG. 15. The force is transmitted to the pre-force member 22 via the outer bottom plate 15 and the anchor device 21, the pre-force member 22 is pulled, and the force is transmitted to the other end plate 16, and then extended by the inner core member 11 and Segment 111 passes the force out. As can be seen from Fig. 5, under the external force F, the outer layer member 13 and the inner core member 11 have a relative displacement δ, which can be dissipated by the energy dissipating plate 112, the energy dissipating plate 132, the angle steel 133 and the bolt 14.

Referring again to Figures 6 and 7. When the device is pulled, the pre-force member 22, the anchor device 21 and the two outer layer bottom plates 15 and 16 are tension members, and the external force is as shown in Fig. 6, and the extension portion 131 of the outer layer member 13 is passed through the outer layer member 13 On the outer bottom plate 16, the force is transmitted to the pre-force member 22 via the outer bottom plate 16 and the anchor device 21, and is pulled, and the force is transmitted to the outer bottom plate 15 of the other end, and then transmitted to the inner core member 11 The extension 111. As can be seen from Fig. 7, the outer layer member 13 and the inner core member 11 have a relative displacement δ under the external force F, and can be dissipated by the energy dissipating plate 112, the energy dissipating plate 132, the angle steel 133, and the bolt 14.

The device uses the restoring force of the pre-force to eliminate residual deformation under earthquake. However, limited by the material properties of the tension member, the axial deformation of the device is limited to δ.
