Embodiment 1

[0033] see figure 1 , a new type of support-type seismic energy dissipator, comprising an anti-buckling device 100 and a core plate 200, the core plate 200 includes a yield section Ly, the two ends of the yield section Ly are transition sections Ltr, and the outside of the transition section Ltr is a node The middle part of the elastic segment Lc, wherein the yield segment Ly of the core plate 200 is disposed inside the anti-buckling device 100 .

[0034] see figure 1 , figure 2 , image 3 , the cross-section of the core plate 200 is a "ten" shape, wherein the cross-section of the yield section Ly and the node elastic section Lc is a constant section, and the cross-section of the transition section Ltr is a variable section. On the core plate 200, an anti-breakage device is provided, and the anti-breakage device includes a stiffening plate 310, a tensile limiting plate 320 and a compressive limiting plate 330, and the stiffening plate 310 is fixed at the transition between...

Embodiment 2

[0037] A new type of support type anti-seismic energy dissipator, this embodiment is the same as the first embodiment in terms of parts composition, structure, fixing and assembly methods, the difference lies in:

[0038] see Figure 10 , the cross section of the core plate 600 is "one" shape. The core plate 600 with a “one”-shaped cross-section includes a main core plate 610, and a group of stiffening plates 620 are respectively arranged at the node elastic section, the transition section and the end of the yield section at both ends of the main core plate 610, so that the core plate 600 The cross-section of the location where the stiffening plate 620 is arranged is in the shape of a "ten".

[0039] see Figure 11 , the anti-buckling device 500 includes two rectangular square tubes or square square tubes 510 clamping the yield section Ly of the "one"-shaped core plate 600 with it. , A layer of packing steel plate 530 is arranged outside the connecting plate 520 . The two ...

Abstract

The invention discloses a novel support seismic energy dissipator, which comprises an anti-bending device, a core plate and an isolating material arranged between the anti-bending device and the core plate. Two ends of the anti-bending device are provided with limiting stressed plates; one end of the core plate is provided with a tensile device consisting of stiffening plates, tensile limiting plates and compression-resistant limiting plates; the middle of a yield section of the core plate is arranged in the anti-bending device, and one end of the core plate is welded with one end of the anti-bending device; the other end of the core plate, which is provided with the tensile device, and the anti-bending device can relatively slide, and the inner sides of the compression-resistant limiting plate and the limiting stressed plate at the end are respectively provided with a rubber bumper; and the outer surface of the core plate, which is matched with the anti-bending device, is provided with the isolating material. After the novel support seismic energy dissipator is deformed to some extent, the rigidity is improved through the anti-bending device, and a support is prevented from constantly deforming or collapsing under the action of a large earthquake; the variable cross-section times of the core plate is reduced, so that the core plate is convenient to process, the sizes of the core plate and the anti-bending device are reduced through the stiffening plates, the material consumption and dead weight are reduced, the structure is optimized and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a novel support type anti-seismic energy dissipator. Background technique [0002] In recent decades, braced anti-seismic energy consumers have been widely used in the field of building structures in the United States, Japan, Taiwan and other countries and regions. The braced seismic energy dissipator is a brace that does not buckle under compression, and has more stable mechanical properties than traditional braces. The buckling-constrained bracing can not only improve the stiffness and ductility of the structure, but also use the hysteretic properties of steel to consume the energy of the horizontal load acting on the structure, which is of great significance to the improvement of the seismic capacity of the structure. By 2008, there were hundreds of buildings supported by buckling restraint in the world, but the domestic research in this area is still in its inf...
