Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steel structure building component and structure engineering, especially to a kind of combined shear wall of buckling-preventing built-in corrugated steel plate. BACKGROUND

[0002] The growth of social economy and the progress of science and technology have enabled great development of high-rise buildings in China in recent years. In high-rise buildings, the lateral resistance of building structures is a major concern for engineering designers. As a lateral resisting component, shear walls have the advantages of high bearing capacity and large lateral stiffness, and have been widely used in high-rise building structures. Buckling-preventing steel plate shear walls, as a kind of assembled energy-dissipating lateral force component with superior performance, are generally arranged in one or more spans of a frame structure. The edges of the wall plate are connected to the frame beams and columns, forming a frame-buckling-preventing steel plate shear wall lateral force system. Thin steel plates are used as the core components for resisting floor shear forces. The steel plates on both sides are clamped by buckling-preventing cover plates connected by bolts. The cover plates limit the out-of-plane buckling deformation of the steel plates, so that the latter always maintains a nearly plane shear stress state. The component as a whole exhibits high bearing capacity and high energy dissipation capacity. During an earthquake, the steel plates in the component enter plasticity before the main frame, thereby playing an energy-absorbing and shock-absorbing function to protect the main frame from damage. After an earthquake, only the non-load-bearing steel plates need to be replaced, and the structure can continue to be used.

[0003] Currently, buckling-preventing steel plate shear walls have become an efficient technical measure for improving the seismic performance of buildings. However, there are still some deficiencies in the engineering application of the component. Due to the thick shear walls and the large number of shear walls in super-high shear wall structures, the use of building functions is affected.

[0004] In the prior art, a patent with publication number CN118007845A discloses a ductile-constrained corrugated steel plate shear wall and a construction method, which includes a corrugated steel plate, a perforated steel plate connector, a concrete constraint layer, and an edge frame. The corrugated form of the corrugated steel plate adopts trapezoidal corrugation, sinusoidal wave, or necked corrugation, with the corrugation ridges placed vertically. The PBL connector includes stiffening ribs and perforated steel bars with openings. The stiffening ribs are made of flat steel plates, H-shaped steel, C-shaped steel, or Z-shaped steel, and are arranged horizontally. The concrete is high-toughness concrete. The ductile-constrained corrugated steel plate shear wall has the advantages of convenient production and construction, superior stability performance, efficient interface connection, and excellent durability, which can significantly improve the seismic toughness of the structure and can be widely applied to offshore floating energy platforms, high-rise assembled buildings, and other lightweight application scenarios under extreme loads or complex environments.

[0005] The patent with the publication number CN118704660A discloses an integrated buckling-restrained shear wall adopting a corrugated steel cover plate, comprising: an integrated wall plate, a hinged support, a fish tail plate and an edge frame. The integrated wall plate comprises: a steel plate, a steel bar truss corrugated plate, an edge stiffening plate and filled concrete. The integrated wall plate uses the plate itself as a permanent concrete pouring formwork and is integrally formed. The wall plate is fixed on the edge frame main body frame through the hinged support and the upper and lower fish tail plates, reducing the workload of traditional wall plate site bolt connection and welding. The wall plate is not connected with the frame column, and is flexible in arrangement and convenient for building opening. The corrugated combined cover plate has strong buckling restraint capacity for the steel plate and a corrosion-resistant surface layer, which is beneficial to improve the structural seismicity and durability. The wall plate structural performance is adjusted by changing the edge stiffening plate and steel plate thickness, avoiding changing the remaining prefabricated module, and the integrated design concept is beneficial to modularization, mass production and green assembly construction.
