Novel support type anti-seismic damper

Abstract

The invention relates to a novel support type anti-seismic damper, comprising an anti-buckling device, a core plate and insulation material, wherein the insulation material is arranged between the anti-buckling device and the core plate. The novel support type anti-seismic damper is characterized in that the anti-buckling device is formed by welding two square steel tubes or rectangle steel tubes by virtue of connecting pieces, wherein the core plate is arranged between the square (rectangle) steel tubes, the two ends of the core plate are vertically provided with stiffening plates, the two ends of the wall the square steel tubes facing the core plate are provided with notches the quantity of which is corresponding to the quantity of the stiffening plates, and the stiffening plates are inserted into the notches. Each stiffening plate can be provided with a limit steel plate which protrudes the square (rectangle) steel tubes, and the outer wall and the limit steel plate on the stiffening plate form a limiting device, thus the support type anti-seismic damper is prevented from failure when design deformation is exceeded. By adopting the support type anti-seismic damper provided by the invention, materials of the core plate and the anti-buckling device are saved, and processing difficulty and production cost are reduced.

Description

technical field [0001] The invention relates to a 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. Howev...

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 leads to a large appearance size of the anti-buckling device, which will have a negative impact on the building's use and function, and will waste materials at the same time, and the self-heavyness of the support

[0008] 4. The out-of-plane stability of the "one"-shaped connection at the end is not good, and out-of-plane damage is prone to occur, resulting in failure of the supporting effect;

[0009] 5. The end stability of the existing steel structure restraint buckling device and the "one"-shaped core plate anti-buckling support and the stability of the anti-buckling device are not reliable enough, and the support is prone to damage under multiple deformations
