Description

Technical Field

[0001] The utility model relates to the technical field of steel plate walls, in particular to a reinforced corrugated steel plate wall. Background Art

[0002] In recent years, the expansion of urban populations, booming economies, and advancements in construction technology have significantly boosted the development of high-rise structures. For traditional structures exceeding 20 stories, relying solely on beam-column flexural joints to resist horizontal lateral forces often requires larger beam and column cross-sections, making them less economical. In these situations, bracing or shear walls are often required to enhance the structure's resistance to horizontal lateral forces, creating a dual lateral force-resisting system.

[0003] Reinforced concrete shear walls are currently the most widely used type of shear wall. However, they are heavy, have poor ductility, are prone to brittle failure, and are difficult to repair after earthquakes. Steel plate shear walls have attracted considerable attention due to their relatively superior lateral stiffness, strength, ductility, and energy dissipation capacity, and are gradually being widely used in high-rise building structures. However, steel plate shear walls also have certain drawbacks. Steel plate shear walls can be divided into two categories: flat steel plate shear walls and corrugated steel plate shear walls. Flat steel plate shear walls exhibit a pronounced "pinching" phenomenon, with out-of-plane buckling deformation increasing significantly with increasing interstory drift. Buckling of flat steel plate shear walls is also accompanied by a loud noise. Corrugated steel plate shear walls will experience out-of-plane buckling failure when the interstory drift angle falls below the elastic-plastic interstory drift angle limit. Once buckling failure occurs, the corrugated steel plate wall's bearing capacity and stiffness degrade, and its energy dissipation capacity is significantly reduced. Therefore, there is an urgent need for a structural member with stable bearing capacity and stiffness, high out-of-plane stiffness, and good economic efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical solution: a reinforced corrugated steel plate wall, comprising a corrugated steel plate located in the center and stiffening ribs arranged laterally on both sides, the two sides of the corrugated steel plate and the stiffening ribs are connected to the columns, the upper and lower ends of the corrugated steel plate and the columns are connected to H-shaped steel, the H-shaped steel is fixed on the frame beam, and the corrugated steel plate, H-shaped steel, columns and stiffening ribs are all fixed by welding.

[0006] Furthermore, the corrugated steel plate includes several standard wave shapes consisting of horizontal segments and oblique segments, the horizontal segment length and the oblique segment length of the standard wave shape are both greater than 50 mm, the angle between the horizontal segment and the oblique segment is greater than 45°, the wave height is 30-50 mm, and the ratio of the wavelength to the wave height of a standard wave shape is less than 6.

[0007] Furthermore, the corrugated steel plate is made by bending a thin steel plate, the corrugations are isosceles trapezoidal and arranged vertically, the thickness is 4-8 mm, and the material is Q235.

[0008] Furthermore, the corrugated steel plate end member wave section is composed of a standard wave shape or a half-wave shape of a standard wave shape.

[0009] Furthermore, the half-wave form of the standard waveform is that the length of the horizontal section and the oblique section are both half of the standard waveform, the angle between the horizontal section and the oblique section is greater than 45°, and the ratio of the wavelength to the wave height of the constructed waveform is less than 6.

[0010] Furthermore, the length of the stiffening rib is consistent with the width of the corrugated steel plate, the thickness is less than 15 mm, the width is 100 mm, and the material is Q355B.

[0011] Furthermore, the columns are made of rectangular cold-bent hollow steel, the interior of which is filled with concrete having a strength greater than C30 without leaving any gaps. The cross-sectional height of the rectangular cold-bent hollow steel is 150-200 mm, and the width is 150-200 mm.

[0012] Furthermore, the H-shaped steel serves as a connecting member between the product and the frame beam, the web of the H-shaped steel is arranged vertically, and the middle surface of the corrugated steel plate is coplanar with the web of the H-shaped steel.

[0013] Furthermore, the H-shaped steel and the frame beam are connected by welding or bolting, and correspondingly, grooves or bolt holes are provided on the flanges of the H-shaped steel.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] In the present invention, a plurality of transverse stiffening ribs are used to restrain the external buckling of the steel plate wall, so that its energy dissipation performance is excellent and the hysteresis curve is full. At the same time, the all-steel structure is lighter than the traditional anti-buckling steel plate wall, and is easy to process, transport, install and subsequently replace. Compared with the case where the waves are arranged horizontally, the advantage of the stiffened corrugated steel plate with the waves placed vertically is that when the height of the corrugated steel plate remains unchanged, its load-bearing and energy dissipation performance will hardly be affected by changes in the width of the steel plate.
