Problems solved by technology

When the gusset plate with high stiffness is closely connected with beams and columns, the stress state of the local components at the connection node is very complicated, and the stress state of the gusset plate itself is also very complicated, and the force transmission in the complex node area may also be It has an adverse effect on the seismic performance of columns and beams; when it is only connected to the beam end, the concentrated axial force of the support will generate a large force on the beam end section, and the beam end section is likely to become a weak surface

Embodiment 1

[0032] Such as figure 1 As shown, this embodiment is a buckling restrained support structure arrangement system used in a new building, and the new building adopts a reinforced concrete structure. It includes frame columns 1, frame beams 2, buckling restraint supports 3 and connecting node elements 4, a rectangle is formed between the frame columns 1 and the frame beams 2 in each span, and the buckling restraint supports in each span 3 is four, and the two ends of each buckling-constrained support 3 are respectively fixed to the middle of the frame column 1 and the frame beam 2 through connecting node elements 4, and the four buckling-constrained supports 3 enclose a rhombus-shaped building window opening, There is no adverse effect on the space in the middle, and it has excellent architectural lighting functions.

[0033] Such as image 3 As shown, the buckling-restrained brace 3 may be a traditional buckling-restrained brace filled with concrete or a pure steel assembled b...

Embodiment 2

[0038] Such as figure 2 As shown, this embodiment is a buckling-constrained bracing structure layout system used in a new building. The new building adopts a steel structure. The difference between this embodiment and Embodiment 1 lies in the fixing method of the gusset plate and the buckling Constraint supports 3 are connected differently from connection node elements 4 .

[0039] In the damping module of this embodiment, the buckling-constrained support 3 is connected to the node element 4 by bolts. Specifically, screw holes are provided on the node plate 4-1 and the energy-dissipating core plate 3-1, and the stiffening plate 4 After -2 is aligned with the stiffener 3-2, use a connecting plate 4-6 that also has screw holes to align with the holes on the node plate 4-1 and the energy dissipation core plate 3-1, and pass through the connecting plate 4-6 Connect the gusset plate 4-1 and the energy dissipation core plate 3-1 together with bolts 4-7. The buckling-constrained s...

Embodiment 3

[0042] Such as Figure 6 As shown, this embodiment is a buckling-constrained bracing structure layout system used in existing buildings, including frame columns 1 of existing buildings, frame beams 2 of existing buildings, buckling-constrained supports 3 and connecting node elements 4, A rectangle is enclosed between the existing building frame columns 1 and the existing building frame beams 2 .

[0043] Such as image 3As shown, the buckling-restrained brace 3 may be a traditional buckling-restrained brace filled with concrete or a pure steel assembled buckling-restrained brace. The buckling-constrained support 3 can be a traditional buckling-constrained support or a double-stage yielding buckling-constrained support. In this embodiment, traditional buckling-restrained braces are used. The buckling restraint support 3 includes an energy dissipation core plate 3-1, a stiffener 3-2 and an outer sleeve 3-3.

[0044] There are four connecting node elements 4 , which are arran...

Abstract

The invention discloses a buckling restrained brace structure arrangement system for a building, which comprises a frame column, a frame beam, four buckling restrained braces and a connecting node element, a rectangle is enclosed between the frame column and the frame beam, and the connecting node element is arranged between the frame column and the frame beam. The two ends of each buckling restrained brace are fixed to the middle of the frame column and the middle of the frame beam through connecting joint elements respectively, and a rhombic building window opening is defined by the four buckling restrained braces. The buckling restrained brace arranged in the rhombus mode is adopted, the good anti-seismic performance is achieved, construction is convenient and fast, the steel using amount of embedded parts is reduced, good feasibility and practicability are achieved, and the buckling restrained brace can be used for concrete structures, steel structures and combined structures. The structure is simple, force transmission is clear, and construction is fast.

Description

technical field [0001] The invention relates to structural shock-absorbing buildings, in particular to a buckling-constrained support structure arrangement system for buildings. Background technique [0002] As we all know, my country is an earthquake-prone country. With the continuous development of academic research and engineering technology in the field of earthquakes in my country, the seismic performance of buildings has been greatly improved. In recent years, buckling-constrained braces are increasingly used in engineering and have achieved remarkable results. Buckling-restrained braces are connected to frame beams and frame columns through connection nodes, and the connection performance of connection nodes often affects the seismic performance of frame beams and frame columns. [0003] At present, the common method of connecting nodes is to extend the gusset plate and embed it at the node of the frame beam and column, or just connect it to the beam end. When the g...
