Problems solved by technology

[0004] However, there are few plastic hinges in the current buckling-constrained energy-dissipating supports, which cannot exert the energy-dissipating capacity of the entire core plate, cannot control the yield point position of the core plate, and cannot control the number of plastic hinges, which makes the energy consumption of the entire support The performance cannot be precisely controlled to achieve the desired effect

Embodiment 1

[0037] as follows Figure 1 to Figure 5 As shown, the present invention is composed of a core barrel 1, a cross gusset plate 2, an end bearing plate 3, a cross fixing plate 4, an inner casing 5, an unbonded material 6, an outer casing 7, an outer casing sealing plate 8, a stiffening The ribs are composed of nine parts. The core barrel 1 is formed by punching steel plates into different simple geometric figures, and then welded to form a cylindrical shape. As shown in FIG. 4 , in this embodiment, the geometric figure on the core barrel 1 is a combination of isosceles triangles. Figure 5 is the crease pattern in this example. like figure 2 As shown, the end pressure plate 3 is connected to the core barrel 1, and the end pressure plate 3 is welded to the four sides of the mouth of the core barrel 1, and the size of the end pressure plate 3 is the same as that of the mouth of the core barrel 1. At the same time, the cross fixing plate 4 is welded on the inner side of the end...

Embodiment 2

[0039]This embodiment is the same as the rest of Embodiment 1, except that the inner and outer double casings are replaced with tubes of other shapes to provide constraints.

[0040] In order to express the spatial structure of the sub-unit more clearly, a space rectangular coordinate system is established to describe the coordinates of each node. The coordinate origin O is the center of the sub-unit, and the straight line where the diagonal line FH of the quadrilateral EFGH is located is taken as the X-axis, pointing from F to H. In the positive direction, take the straight line where the other diagonal line EG of the quadrilateral is located as the Z axis, pointing from E to G as the positive direction, and take the straight line passing through the point O and perpendicular to the X axis and Z axis as the Y axis, and the positive direction is the slave surface ABCD Pointing to face IJKL.

[0041] The size of the energy dissipation unit should meet the following conditions (...

Abstract

The invention discloses an internal and external double-sleeve restraining folded steel plate energy-consuming support. The support comprises a core cylinder, an internal sleeve arranged in the core cylinder, end pressure bearing plates arranged at cylinder openings in the two sides of the core cylinder, a cross-shaped fixing plate arranged in the internal sleeve and connected with the inner sides of the end pressure bearing plates, cross-shaped plates connected to the outer sides of the end pressure bearing plates, an external sleeve arranged outside the core cylinder in a connected mode, and external sleeve sealing plates connected to the two ends of the external sleeve. The core cylinder is formed by sequentially connecting multiple energy-consuming units. The good post-yielding energy-consuming ability of the support is utilized for reducing earthquake response to buildings, and the support is easy to manufacture, convenient to install and capable of being applied to the structure seismic aspect, and effectively reduces earthquake disasters.

Description

technical field [0001] The invention belongs to the field of energy-dissipating supports of building structures, and relates to an energy-dissipating support of folded steel plates constrained by inner and outer double casings. Background technique [0002] An earthquake is a strong natural disaster, and the energy released during an earthquake can cause fatal damage to buildings. In order to absorb the energy released during an earthquake to protect buildings, avoid damage to buildings caused by excessive energy input, and protect people's lives and property, buckling restraint support devices are widely used. [0003] The buckling restrained brace is mainly composed of core plate, outer casing, unbonded material and other parts. In this technology, the core plate is the main force-bearing unit, and the core plate deforms under the action of an earthquake to consume the energy input by the earthquake, so as to achieve the purpose of protecting the main frame. The inner an...
