Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a replaceable steel connecting beam double-layer steel plate high-strength concrete composite shear wall. Background Technology

[0002] In the field of building engineering, shear walls, as an important lateral force resisting component, are widely used in high-rise building structures to resist the effects of horizontal forces such as earthquakes and wind loads. Traditional shear wall designs mostly employ reinforced concrete structures; however, with the increase in building height and the diversification of functional requirements, higher demands are placed on the performance of shear walls. For example, in high-intensity earthquake zones or areas prone to strong typhoons, traditional single-layer steel plate-concrete composite shear walls, due to their insufficient stiffness and poor ductility, are unable to meet the high standards of safety and durability required by modern buildings.

[0003] To address these issues, researchers have proposed a series of improvements, such as combining double-layer steel plates with concrete, aiming to enhance the overall strength and seismic performance of shear walls. However, existing double-layer steel plate shear walls have some shortcomings: firstly, the connection method between the double steel plates is relatively fixed, resulting in high repair costs and time consumption if damage occurs; secondly, some design schemes fail to fully consider the overall stability of the structure under complex stress states, leading to limitations in practical applications.

[0004] Furthermore, existing shear walls often neglect the effective utilization of the hollow cavity and fail to fully consider the selection of the infill material and its impact on shear strength and bending capacity. This not only affects the overall performance of the structure but also limits the adaptability of the shear wall under different working conditions. Meanwhile, how to improve the local strength and toughness of key components through simple and effective measures is also an important direction of current research. Therefore, this invention proposes a replaceable steel-coupling double-layer steel plate high-strength concrete composite shear wall. Utility Model Content

By optimizing the design and connection method of the double-layer steel plates and rationally setting up reinforcing concrete layers, the shear strength and bending capacity of the shear wall are improved. This structure not only enhances the overall structural stability but also enables convenient replacement of key components, significantly reducing maintenance costs. Furthermore, this invention introduces carbon fiber fabric layers in specific locations, further enhancing the structure's toughness and durability, enabling it to better adapt to various complex engineering environments.
