Problems solved by technology

However, due to the lack of seismic performance of short-limb shear walls, the application in earthquake areas is limited. How to improve the seismic performance of short-limb shear walls has become one of the research hotspots in many universities and research institutes.
Many scholars have shown through theoretical and experimental research that for short-limb shear walls with T-shaped and L-shaped sections, when the section flange is on the tension side, the ductility and energy consumption of the wall are poor, and its seismic performance is weak, which causes this phenomenon The reason is that when the flange of the section is on the tension side, the configuration of the longitudinal reinforcement of the web is asymmetrical, and the longitudinal reinforcement on the flange side is obviously higher than the end of the web, thus reducing the seismic performance of the wall

Embodiment 1

[0012] Embodiment one: Such as figure 1 As shown, the present invention is beneficial to the earthquake-resistant local seam short-limb shear wall, and the plastic hinge area at the bottom of the wall of the short-limb shear wall is provided with a vertical seam that runs through the wall, and the vertical seam is vertical from the bottom of the wall. Formed by extending upwards, the height of the vertical joint is within the range of the height of the plastic hinge of the wall. In this embodiment, the short limb shear wall is a short limb shear wall with a T-shaped section, and the vertical joints on the short limb shear wall with a T-shaped cross section include plastic hinge areas respectively arranged on the flange walls on both sides of the web. Vertical seam I (B) and vertical seam II (C) above, vertical seam I (B) and vertical seam II (C) are respectively set in the plastic hinge area at the bottom of the flange wall, and are perpendicular to the bottom of the flange ...

Embodiment 2

[0014] Embodiment two: Such as figure 2 As shown, the difference from Embodiment 1 is that in this embodiment, the short-leg shear wall is an L-shaped cross-section short-leg shear wall, and the vertical joints on the L-shaped cross-section short-leg shear wall include Vertical joints III (K) and vertical joints IV (P) on the plastic hinge areas of the two wall piers, vertical joints III (K) and vertical joints IV (P) are respectively set in the plastic hinge areas at the bottom of the respective walls, And it is formed by vertically extending upwards from the bottom of the wall bodies where they are located. The heights of the two vertical joints are within the range of the plastic hinge height of the wall.

[0015] Analysis of the principle of the present invention: before the vertical joints are set in the L-shaped cross-section short limb shear wall, when the horizontal force acts along the wall limb AE and the wall limb AC is on the tension side, the longitudinal rein...

Abstract

The invention is beneficial to the earthquake-resistant local jointed short-limb shear wall, and relates to the technical field of structural engineering. The invention is advantageous to the earthquake-resistant local jointed short-limb shear wall. A penetrating wall is arranged in the wall plastic hinge area of ​​the short-limb shear wall. body vertical seams. When the short-leg shear wall is a T-shaped cross-section short-leg shear wall, the vertical joints on the T-shaped cross-section short-limb shear wall include the vertical joints I respectively arranged on the plastic hinge area at the bottom of the flange wall on both sides of the web. and vertical joint II, vertical joint I and vertical joint II are respectively formed by extending vertically upward from the bottom of the plastic hinge area of ​​the flange wall where they are located; The vertical joints on the short-section shear wall include vertical joints III and IV respectively arranged on the plastic hinge area at the bottom of the two wall bases. The bottom end of the plastic hinge area of ​​the wall is formed by extending vertically upwards. The invention can effectively improve the seismic performance of the short limb shear wall.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to short-limb shear walls which are beneficial to earthquake resistance. Background technique [0002] As people have higher and higher requirements for the plane and space of residential buildings, especially high-rise residential buildings, the original ordinary frame structure with exposed beams and exposed columns, and ordinary shear wall structures can no longer meet people's requirements for residential space in modern society. Therefore, on the basis of the original shear wall, a high-rise residential structure type that can adapt to people's new housing concept has been gradually developed, that is, "short-leg shear wall". It overcomes the shortcomings of ordinary frames and ordinary shear walls, and has been affirmed by architects, and welcomed by residents and housing developers all over the country. However, due to the insufficient seismic performance of s...
