A steel plate combined shear wall

Abstract

The invention discloses a composite shear wall with a super-thick steel plate. The composite shear wall comprises a concrete wall body and the super-thick steel plate embedded into the concrete wall body, wherein two sides of the super-thick steel plate are both evenly provided with long studs; general short studs are evenly arranged between every two adjacent long studs; the length L of each long stud is that L is less than or equal to h-a and more than d, wherein d is the length of each general short stud, h is the thickness of the concrete wall body on which the long studs are positioned, and a is the thickness from the outmost layer of reinforcing mesh to the outer surface of the wall body in the concrete wall body. According to the composite shear wall, mechanical bit force and friction force between the steel plate and concrete can be enhanced by the long studs, the area of the concrete is prevented from being increased by a long stud anchoring area, the steel plate and the concrete wall bodies on two sides are prevented from separating to enhance a joint function of the steel plate and the concrete wall bodies, and a technical scheme that the long studs and the short studs are mixed is adopted to improve the integrality of the composite shear wall of the steel plate. The composite shear wall of the super-thick steel plate has the advantages of definite force transferring, simple construction, convenience in construction and good integral ductility of a construction member and is favorable for improvement of the connection quality.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to an ultra-thick steel plate combined shear wall. Background technique [0002] The steel plate composite shear wall has the advantages of high bearing capacity, light weight, fast construction speed and good shear performance, and is especially suitable for high-rise and super high-rise buildings and seismic reinforcement projects in high-intensity areas. The superior performance in seismic performance makes it widely used in the field of super high-rise buildings. However, the research on steel plate composite shear walls is not mature at home and abroad. There are no relevant calculation provisions in the code for the connection method of steel plate and concrete, and the connection structure of steel plate and concrete directly affects the interaction between the two and the stability of the structure. And safety, but also affect the amount of structural steel a...

AI Technical Summary

Problems solved by technology

Its main disadvantages are: the reinforced concrete walls on both sides of the steel plate are relatively thick, and the shear studs are short, which is not enough to ensure the joint work between the concrete and the steel plate in the area other than the studs; holes, and the holes lead to the weakening of the steel plate. At the same time, the steel bars piercing the plate are all equipped with hooks. The construction of the steel bars passing through the steel plate is difficult, the construction quality is difficult to guarantee, the construction progress is slowed down, and the construction cost is increased.
