Abstract

The invention discloses a bearing and energy-dissipation difunctional corrugated steel plate wall. The bearing and energy-dissipation difunctional corrugated steel plate wall comprises a buckling-freecorrugated steel plate energy-dissipation wall located in the center and square steel pipe concrete column members located at the two sides, the buckling-free corrugated steel plate energy-dissipation wall is welded to the square steel pipe concrete column members at the left side and the right side, the upper ends and the lower ends of the square steel pipe concrete column members are welded tobase plates respectively, and the base plates are fixed to frame beams. The bearing and energy-dissipation difunctional corrugated steel plate wall is connected with a main body structure through bolts, the convenience and assembly degree of on-spot installation are improved, and the on-spot welding workload is reduced. The bearing and energy-dissipation difunctional corrugated steel plate wall integrates load bearing and earthquake-resistance energy dissipation, and the shear capacity and the stability of the structure can be improved; when the bearing and energy-dissipation difunctional corrugated steel plate wall is subjected to plastic energy dissipation, an additional damping ratio is provided, the response under a structure earthquake is reduced, the weight can also be borne, part ofupper vertical loads borne by the columns are shared, and the purpose that the wall has two functions is achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a corrugated steel plate wall with dual functions of load bearing and energy consumption. Background technique [0002] High-rise buildings will occupy an increasingly important position in the future construction industry, and the selection of lateral force-resistant structural components in high-rise buildings is very important. Traditional lateral force resistant structural components mainly include shear walls, steel supports, etc., but these can no longer meet the needs of super high-rise buildings for structural seismic capacity. In response to this situation, many new structural energy-dissipating components have emerged as the times require. Examples include viscous damped walls, buckling-resistant steel walls, and shear-type dampers. [0003] For steel plate walls, flat steel plates are generally used. However, due to the small out-of-plane stiffness ...

AI Technical Summary

Problems solved by technology

However, due to the small out-of-plane stiffness of the flat steel plate, out-of-plane buckling will occur under the action of a small horizontal force, resulting in low stiffness and limited hysteretic performance.

Most of the built-in structures of steel plate shear walls in the prior art are flat steel plates, and their vertical bearing capacity, lateral resistance and buckling capacity are all low. After an earthquake, the steel plate wall is prone to deformation and energy consumption.

If the deformation is not serious, it needs to be repaired before it can be used again; but if the deformation is serious, it cannot be repaired, and the built-in steel plate needs to be replaced, which will increase the cost

On this basis, if out-of-plane restraint plates or stiffeners are used to improve the out-of-plane stiffness of such components, there are still a series of problems such as reduced economy and complex processing.
