Description

Technical Field

[0001] The utility model belongs to the technical field of building structure engineering, in particular to a truss side column type load-bearing and energy-consuming dual-function corrugated steel plate wall. Background Art

[0002] Earthquakes are natural disasters that can cause serious damage to buildings and infrastructure, threatening people's lives. In traditional earthquake-resistant design, the stiffness and strength of the structure are often used to improve the earthquake resistance of the building. However, this method may cause the structure to be too rigid, resulting in a large earthquake response force, thereby increasing the stress of the structure and foundation. In order to solve this problem, many new types of structural shock-absorbing and energy-absorbing components have been put into use to reduce the seismic response of the structure. In order to improve the seismic performance of buildings and reduce the impact of earthquakes on structures, corrugated steel plate walls are widely used in building structures as a very effective shock-absorbing and energy-dissipating component.

[0003] For traditional corrugated steel plate walls, the side columns are mostly made of steel side columns with solid webs or straight steel side columns. The straight steel side columns have low stiffness and weak out-of-plane restraint capacity for the internal corrugated steel plates. Under small earthquakes, their sides are prone to buckling, resulting in reduced stiffness of the corrugated steel plate wall and reduced hysteresis performance. Although the side columns use steel with solid webs to improve the restraint capacity of the side columns on the internal corrugated steel plates, the overall force of the side columns is uneven and discrete, and the stress shared by the middle height position of the energy dissipator is small, resulting in low overall steel utilization and poor economic benefits. In engineering, in order to avoid buckling of the sides, stiffening ribs are also set on the side of the side columns, but this increases the amount of steel used and the number of processes, which is not conducive to on-site construction and installation.

[0004] At the same time, the side columns of traditional corrugated steel plate walls have the problems of complex construction methods, inconvenient repair and installation. After an earthquake, the side columns are easily damaged. If the damage is not serious, tedious repair work is required before they can be used again; if the damage is serious, they need to be replaced as a whole. The traditional side column model has many processing steps and if it is damaged, it is an overall damage, which is very serious and very difficult to repair and replace. Based on the above problems, there is an urgent need for a shock-absorbing and energy-absorbing component with large out-of-plane stiffness, superior energy consumption performance, good economy, convenient construction and production, and conducive to assembly installation and production. Utility Model Content

[0005] The utility model aims at the above technical problems and provides a truss side-column type load-bearing and energy-dissipating double-function corrugated steel plate wall. This wall can not only provide lateral stiffness for the structure, improve the energy-dissipating performance of the structure, share part of the vertical load of the structure, and make the structure safer and more stable, but also has good material utilization rate, easy repair and construction. This structure can improve the economy of components on the premise of ensuring component performance and has broad application prospects. The technical solution adopted by the utility model is as follows:

[0006] A truss side-column type load-bearing and energy-dissipating double-function corrugated steel plate wall, comprising upper and lower connecting plates, truss side-column members, corner steel plate braces, and non-buckling energy-dissipating corrugated steel plates;

[0007] The main support structure of a truss side-column type load-bearing and energy-dissipating double-function corrugated steel plate wall is two truss side-column members. The two ends of the truss side-column members are fixed to the upper and lower connecting plates. The left and right sides of the non-buckling energy-dissipating corrugated steel plates are connected to the truss side-column members, and the upper and lower sides are connected to the upper and lower connecting plates. A total of four groups of corner steel plate braces are arranged outside the column feet of the truss side-column members. Each group of corner steel plate braces consists of two front and rear inclined steel plates. One end of the corner steel plate brace is fixed to the truss side-column member, and the other end is fixed to the upper and lower connecting plates.

[0008] Furthermore, the non-buckling energy-dissipating corrugated steel plate is formed by folding a steel plate. The waveform includes a middle standard waveform section and an end structural waveform section. The non-buckling energy-dissipating corrugated steel plate is located in the center of the corrugated steel plate wall.

[0009] Furthermore, the truss side-column member consists of two parallel vertical steel plates and an internal steel truss inside; the internal steel truss contains several steel pipes or steel bars, which are distributed in the truss side-column member in a cross arrangement form.

[0010] Furthermore, the corner steel plate brace is made of mild steel, and the edge line type of the corner steel plate brace is a straight line.

[0011] Furthermore, the upper and lower connecting plates can be connected to the main structure by high-strength bolts through bolt holes, or can be fixed between the upper and lower frame beams by welding.

[0012] The beneficial effects of the utility model:

[0013] The corner braces are beneficial to reducing the buckling of the side columns and participating in the energy dissipation of the components through deformation;

[0014] It can realize the factory prefabrication and standardized production and installation of the corrugated steel plate wall, which is beneficial to realizing the assembly construction on site;

[0015] This structure uses corrugated steel plates, which have a relatively large out-of-plane stiffness and are less likely to buckle out of plane compared to flat steel plates. It can avoid using means such as out-of-plane restraint plates, thick steel plates, and stiffeners to improve the out-of-plane stiffness. Its processing is relatively simple, the processing cycle is short, the economy is high, and it effectively improves the stiffness, bearing capacity, and energy dissipation capacity of the steel plate wall;

[0016] The side columns on both sides of this structure use truss-type side columns, which effectively reduce the steel consumption of the side columns, improve the material utilization rate of the components on the premise of ensuring excellent seismic performance of the components, and have good economy. At the same time, when the side columns are damaged, partial repairs can be carried out for their partial damage, which is more convenient for on-site repair construction, avoiding the overall replacement of the components to reduce the repair amount. The truss-type side columns can be prefabricated and produced standardized in the factory, avoiding the construction inconvenience brought by the on-site pouring of concrete for traditional side columns, which is conducive to the realization of assembly construction;

[0017] Under the action of small earthquakes, this structure is in the elastic working stage and can provide a certain additional stiffness for the main structure; under the action of medium or large earthquakes, the corrugated steel plate wall reaches yield prior to the main structure and enters the elastoplastic working stage. The shear hysteretic deformation of the corrugated steel plate is used to dissipate the energy input into the structure by the earthquake, reduce the seismic response of the structure, and thus reduce the damage of the earthquake to the structure. This structure can not only effectively dissipate the action of the earthquake, but also bear part of the vertical load, which can better ensure the safety of the structure.

Detailed Description of the Preferred Embodiment

[0023] In order to further illustrate the present utility model, the present utility model will be described in detail below in conjunction with the drawings and embodiments, but they should not be construed as limiting the protection scope of the present utility model. Embodiment

[0024] As Figures 1-4 shown, a truss edge column type load - energy dissipation dual - function corrugated steel plate wall of the present utility model includes upper and lower connecting plates 1, truss - type edge column members 2, corner steel plate braces 3, and non - buckling energy - dissipation corrugated steel plates 6.

[0025] The truss - type edge column members 2 are fixed to the upper and lower connecting plates 1 by welding. The non - buckling energy - dissipation corrugated steel plates 6 are connected to the left and right truss - type edge column members 2 and the upper and lower connecting plates 1 by welding. A corner steel plate brace 3 made of mild steel is arranged outside the column foot of the truss - type edge column member 2. One end of the corner steel plate brace 3 is welded to the truss - type edge column member 2, and the other end is welded to the upper and lower connecting plates 1.

[0026] The non - buckling energy - dissipation corrugated steel plates 6 are formed by folding steel plates. The waveform includes a middle standard waveform section and end structural waveform sections. The middle standard waveform section consists of multiple horizontal sections and inclined sections. The end structural waveform sections are composed of standard waveforms or half - wave forms of standard waveforms. The non - buckling corrugated steel plates 6 will not undergo out - of - plane buckling before reaching the ultimate bearing capacity, and the hysteresis curve shows a full - filled characteristic, having a strong energy - dissipation capacity.

[0027] The internal steel truss 5 includes several steel pipes or steel bars, which are distributed in the truss - type edge column members 2 in a cross - arranged form.

[0028] The upper and lower connecting plates 1 are provided with bolt holes 4, and can be connected to the frame beam by high - strength bolts or by welding.

[0029] When installing this structure, operations should be carried out in accordance with the design requirements and the load limits of the materials, and the bearing capacity of the corrugated steel plates and connectors shall not be exceeded to prevent the instability or collapse of the structure.

[0030] A truss edge column type load - energy dissipation dual - function corrugated steel plate wall is installed between the upper and lower frame beams. The inter - story displacement of the floor occurring during an earthquake causes the non - buckling energy - dissipation corrugated steel plates 6 located in the center to undergo plastic shear deformation. In the case of minor earthquakes, this structure can provide a certain additional stiffness for the overall structure; in the case of moderate or major earthquakes, this structure reaches yield prior to the main structure, and utilizes the shear hysteresis deformation of the corrugated steel plates to dissipate the externally input seismic energy, reducing the seismic response of the structure, and thus reducing the seismic damage to the structure.

[0031] The above - mentioned is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
