Novel support-type anti-seismic damper

Abstract

The invention relates to a novel support-type anti-seismic damper which comprises a buckling prevention device, a core plate and isolation material, wherein the isolation material is positioned between the buckling prevention device and the core plate; the novel support-type anti-seismic damper is characterized in that the buckling prevention device is formed by combining two pieces of [-shaped steel by a connecting piece in a welding way; one ends of the two pieces of [-shaped steel are respectively provided with a large-deformation protecting part; the core plate is positioned between the two pieces of [-shaped steel; the two ends of the core plate are respectively provided with a vertical stiffening plate; the two ends of the buckling prevention device are respectively provided with a rabbet, and the number of the rabbets is equal to that of the stiffening plates; and the stiffening plates are inserted into the rabbets. According to the novel support-type anti-seismic damper, the end part of the core plate is designed into a cross-shaped or double-cross-shaped cross section in a reinforcing way, so that the reliability of connection and the stability of support at the end part can be enhanced, the material consumption of the core plate and the buckling prevention device can be reduced, the rigidity of the buckling prevention device is fully utilized, the cross section of the buckling prevention device is reduced, the material consumption is reduced, and the influence on the use function of a building can be reduced at the same time.

Description

technical field [0001] The invention relates to a novel support type anti-seismic energy dissipator, in particular to a novel support type anti-seismic energy dissipator with simple processing and stable performance. Background technique [0002] In recent decades, braced anti-seismic energy consumers have been widely used in countries and regions such as the United States, Japan, and Taiwan. The braced anti-seismic energy dissipator is a brace that does not buckle under tension and compression, and has more stable mechanical properties than traditional braces. The support-type anti-seismic energy dissipator 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 structure due to the horizontal load, which is of great significance to the improvement of the anti-seismic capacity of the structure. [0003] By 2008, there were hundreds of buildings with braced anti-seismic energy consumers....

AI Technical Summary

Problems solved by technology

[0005] 1. The consumption of the core plate and the anti-buckling device is large;

[0006] 2. In some cases, the core board needs to change the cross section multiple times, and the manufacturing process is complicated;

[0007] 3. The appearance size of the anti-buckling device is large

In order to achieve the constraints on the non-yielding section, the appearance size of the component causes the appearance size of the anti-buckling device to be very large, which will have a negative impact on the building's use function, and will waste materials, and the self-heavyness of the support;

[0008] 4. The stability of the anti-buckling device of the "one"-shaped core plate section is not good, and it is easy to cause damage to the anti-buckling device

In addition, the out-of-plane stability of the connection at the support end is not good, and out-of-plane damage is prone to occur, resulting in failure of the support function.

[0009] 5. The anti-buckling device of pure steel structure is prone to local damage
