Problems solved by technology

In practical applications, in order to give full play to the performance of steel plates, ensure that the hysteresis loop is full, and enable pure shear yield failure to occur when the steel plate shear wall is stressed, it is usually necessary to set sufficient transverse and longitudinal stiffeners on both sides of the steel plate shear wall. , to ensure that the overall buckling and local buckling of the steel plate do not occur before yielding, which greatly increases the complexity of the design, manufacture and construction of the steel plate shear wall

Embodiment approach

[0042] The specific assembly implementation method of the bionic steel plate shear wall of the present invention is as follows:

[0043] Schematic diagram of the bionic steel plate shear wall model and its detailed structure figure 1 ,2,3,4 shown. According to the commonly used building shear wall size and stress conditions, this manual reserves the bolt hole spacing of the steel plates on both sides and the interlayer according to the seismic fortification intensity of the area. The first step is to press the unit polygon grille with semicircle into the Figure 5 As shown, use bolts to connect and install (the bionic honeycomb core layer has a variety of manufacturing processes, this specific embodiment only provides one as an example, and it can also be connected by adhesive, one-time molding, snap-fit ​​connection, etc.); the second step Fix the A and B steel plates on both sides with bolts, see the assembly process Figure 6 ; The third step is to transport the correspo...

Abstract

The invention discloses a steel plate shear wall which comprises a shear wall body composed of two oppositely-arranged steel plates and a biomimetic core layer. The biomimetic core layer is a polygonal honeycomb, polygonal honeycomb cells are connected with the shear wall body through fasteners, and the polygonal honeycomb is composed of polygonal honeycomb cells mutually connected in a plane. The biomimetic steel plate shear wall can effectively improve the bending resistance performance, flexural properties, deformation energy-dissipating capacity under the earthquake action and other mechanical property indexes of the steel plates. An applicant conducts three-dimensional finite element analysis on the biomimetic steel plate shear wall structure, and the outside-plane flexural properties and deformation energy-dissipating capacity of the biomimetic steel plate shear wall are 1.8-2.3 times of the properties of traditional steel plate shear walls under the condition that two types of steel plate shear walls are equal in mass.

Description

technical field [0001] The invention relates to a steel plate shear wall, which belongs to the field of building structures. Background technique [0002] Since the 1980s, my country has adopted steel structures in high-rise buildings, especially super high-rise buildings. Compared with other structures, high-rise steel structures have relatively significant advantages in terms of use function, design, construction and comprehensive economy. In addition, steel output The continuous improvement of the steel structure research, design, production and installation team has also made the development of high-rise steel structures in my country have a bright future. [0003] At present, the lateral force resistance systems often used in high-rise steel structures mainly include giant structure systems, frame structure systems, frame-support structure systems, shear wall structure systems, frame-shear wall structure systems, and frame-support-shear wall systems. Structural system a...
