Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, the buckling-constrained support member of Embodiment 1 includes: a core part 10 , an external constrained part 20 , two end plates 30 and two support end nodes 40 .

[0025] Wherein, the external constraint part 20 is arranged outside the core material part 10 for constraining the core material part 10 ;

[0026] Two supporting end nodes 40 are respectively arranged at the two ends of the core part 10; as figure 1 As shown, the inner end of the supporting end node 40 is located in the outer restraint part 20 and spliced ​​with the end of the core material part 10, and the outer end of the supporting end node 40 passes outside the end plate 30; the end plate 30 and The supporting end nodes 40 collectively close the ends of the outer constraining portion 20 .

[0027] see figure 2 and image 3 The outer constraining part 20 has a middle cavity 23 which accommodates the core part 10 and extends longitudinally, and a first sid...

Embodiment 2

[0037] The difference between embodiment 2 and embodiment 1 lies in: the construction methods of the first side cavity and the second side cavity are different.

[0038] see Figure 5 , a schematic diagram of the longitudinal section structure of the buckling-constrained support member in Example 2 of the present invention. It can be seen that the first side cavity is divided into two first side sub-cavities 21', and the second side cavity is divided into upper and lower sub-cavities. Two second side sub-cavities 22'. The two first side sub-cavities 21' and the two second side sub-cavities 22' are hollow cavities, that is, both the first side cavities and the second side cavities are discontinuous hollow cavities.

[0039] Specifically, in this embodiment, the external constraint part 20' includes two first sub-rectangular tubes (not marked in the figure) that are stacked up and down and have a first side sub-cavity 21', two stacked up and down A second sub-rectangular tube ...

Abstract

The invention provides a light weight buckling restrained brace member based on a partial filling mode, under the circumstance of no increase of buckling restrained brace materials and manufacturing costs, the weight of the brace member is greatly decreased; the size of each cavity of external restraint part can be adjusted according to design requirements, and design methods can be very flexible;standardized parts such as a rectangle pipe and the like can be more convenient to adopt, the standardization degree of parts of the buckling restrained brace member is improved, and manufacturing ismore convenient.

Description

technical field [0001] The invention belongs to the field of building structure support, and in particular relates to a buckling constrained support member used for support in a building structure system. Background technique [0002] Buckling-restrained brace, also known as unbonded brace, is a new type of seismic energy-dissipating component with superior performance. It consumes the input energy of the earthquake through the yield hysteresis of the metal, thereby slowing down the damage of the main structure. It can be used as a support member that can achieve yield under pressure, which improves the shortcomings of traditional supports that buckle under pressure. It can be used as a structural lateral force-resistant member and energy-dissipating member or as a load-bearing member that bears static loads. In recent years, it has been used in my country get more applications. [0003] Generally speaking, buckling-restrained bracing members include elastic connection sectio...
