How does a shear wall structure compare with a column structure?

The column structure you are talking about is the frame structure.

Frame structure housing refers to the housing made of reinforced concrete poured into load-bearing beams and columns, and then assembled by prefabricated aerated concrete, expanded perlite, pumice, vermiculite and other lightweight plate partition walls. The frame structure is characterized by providing flexible space for the building, but the seismic performance is poor. It is suitable for large-scale industrial construction, with high efficiency and good project quality.

Shear wall refers to the wall that resists horizontal shear force added in the frame structure. It is to replace the beams and columns in the frame structure with reinforced concrete wall panels, which can bear the internal forces caused by various loads, and can effectively control the horizontal force of the structure. Because the horizontal shear force to be resisted by high-rise buildings is mainly caused by **, the shear wall is also called the seismic wall.

The "type of residential structure is a shear wall structure" means that the seismic wall in the residential structure is a shear wall. Pure shear wall structure means that the whole building adopts shear wall structure, including wall body, wall columns (dark columns and end columns), wall beams (connecting beams, dark beams, border beams).

The shear wall structural system has a good bearing capacity, and has a good integrity and spatial effect, and has a better lateral force resistance than the frame structure, so it can build a tall building.

However, the spacing of the structure is limited, so it is impossible to make the bay too large. It is not suitable for large spaces. Flexibility is poor.

Generally applicable to homes, apartments and hotels. At the same time, the floor structure of the structure is generally made of flat plate, and no beam can be set, so the space utilization is better, and the floor height can be saved.

It's already clear upstairs.

There are many modes of walls, such as section only shear walls, load-bearing walls, etc., but what is a shear wall? Some people don't understand the content of this type of wall and don't know what type it is. Many people do not know the content of the specific structure very well when distinguishing the shear wall, and the general shear wall structure has columns?

1. What is a shear wall?

Shear walls are also known as wind-resistant walls, seismic walls, or structural walls. Walls in houses or structures that are mainly subjected to horizontal and vertical loads (gravity) caused by wind loads or ** actions to prevent structural shear (shear) damage. Also known as earthquake-resistant walls, they are generally made of reinforced concrete.

It is divided into plane shear wall and cylinder shear wall. Plane shear walls are used in riser structures, reinforced concrete frame structures, and beamless floor systems. In order to increase the stiffness, strength and collapse resistance of the structure, reinforced concrete shear walls can be cast in situ or prefabricated in some parts.

The cast-in-situ shear wall is poured at the same time with the surrounding beams and columns, and the integrity is good. The cylinder shear wall is used in high-rise buildings, high-rise structures and suspension structures, and is surrounded by the partition walls of stairwells, elevator rooms, equipment and auxiliary rooms, and the cylinder walls are cast-in-place reinforced concrete walls, and its stiffness and strength can bear larger horizontal loads than the plane shear walls.

2. Does the shear wall structure have columns?

From the appearance alone, it is not certain, but there are the following rules to follow. The frame structure is generally not high with 7 or 8 floors, otherwise it is not economical to build, and the frame structure is mainly used in office buildings, multi-storey factories, supermarkets and other large space buildings, and there are also used for residential buildings, so it must appear less. The shear wall structure is generally used for high-rise residential buildings and high-rise office buildings, and the shear wall structure can have no frame columns, or a small number of columns.

There is also a structure called frame shear wall structure, which has both frame columns and shear walls, which can not only create a large space, but also achieve a relatively high building height. (The frame-core tube is also a frame-shear structure, and the core tube is the shear wall).

Wall columns in a shear wall structure are generally not frame columns. Because there is no frame system in the pure shear wall structure of the load-bearing structural system of the house building, and of course there will be no frame columns. There are generally two kinds of columns in the construction of pure shear wall structure, one is the structural column in the brick masonry according to the specification or design requirements, and the other is the dark column in the shear wall.

Both of these columns are not frame columns.

At present, the load-bearing structure system of many and high-rise housing buildings in China mainly includes several forms such as frame shear wall structure, frame cylinder structure (frame tube structure), frame cylinder shear wall structure, etc., and simple shear wall structure is relatively rare. If there are columns in the load-bearing system, they are generally frame columns.

What is a Shear Wall? Shear walls have the effect of wind and earthquake resistance, and play a very important role in stabilizing the safety of indoor buildings. Do shear wall structures have columns?

When decorating, if the owner does not understand the structure of the shear wall, there is no need to know too much about the decoration and cause trouble.

What is the specific content of the characteristics of the shear wall structure system, the following Zhongda Consulting will answer for you.

The capacity of the shear wall to bear both vertical and horizontal loads is large. It is characterized by good integrity, lateral stiffness, small lateral displacement under the action of horizontal force, and because there are no beams, columns and other exposed and protruding, it is convenient for the internal layout of the room. The disadvantage is that it does not provide a large space house.

Poor structural ductility.

When a large space is needed in the basement or the lower part of the basement or several floors (such as shopping malls, parking garages, etc.), a partial frame-supported shear wall structure is formed. in the frame. The transition layer of the shear wall structure and the shear wall structure must be set up with a conversion layer.

Due to the large ability to withstand both vertical and horizontal forces and the large lateral stiffness, the shear wall structure can build a building with a higher and more floors than the frame structure. However, the Orange Hall can only be a house with small rooms, such as residences, hotels, and single dormitories. And in the hotel, you need a foyer with a large space.

Restaurants, shopping malls, etc., are often set up in separate building units.

In order to apply the horizontal force (or ** action) in any direction, for a rectangular plane, the shear wall should be set with volts in both vertical and horizontal directions; For circular planes, shear walls should be set in the radial and circumferential directions; The triangular plane should be along the direction of the three main axes.

Set up the shear wall.

The lateral deformation of the shear wall knot carrying structure under the action of horizontal force is characterized by a curved type.

What are the characteristics of shear wall structure?

A shear wall structure is a structure that uses the interior or exterior walls of a building to make shear walls to bear vertical and horizontal loads. Shear walls are generally reinforced concrete walls that can be the same height and width as the entire building. Because the main reload it bears is the horizontal load, which makes it subject to shear and bending, it is called a laborious wall, so as to distinguish it from the wall that generally bears vertical load.

The lateral stiffness of the shear wall structure is large, the deformation is small, and it is both load-bearing and enclosure, which is suitable for residential and tourist buildings. In foreign countries, the construction of shear walls has reached 70 floors, and residential buildings up to 100 to 150 floors can be built.

Because the spacing of the shear force number Li wall is generally 3 8m, the building layout and use requirements are limited to a certain extent, and it is usually difficult to meet the requirements for buildings that need larger space. The shear wall structure can be pounded on site or prefabricated and assembled. The prefabricated large-scale wall panel structure and box structure are also shear wall structures in essence.

Shear wall, also known as wind-resistant wall or seismic wall, is mainly used to bear the horizontal load caused by wind load or action in the building to prevent structural shear breakage and anti-matching, divided into plane shear wall and three-dimensional shear wall, generally built with reinforced concrete and cast-in-place reinforced concrete.

The frame shear wall structure is also called the frame shear structure, literally speaking, a certain number of shear walls are arranged in the frame structure to constitute a flexible and free use of space, and the force is characterized by the force form composed of two different lateral force resistance structures of the frame and the shear wall structure, and the interaction force between the frame and the shear wall makes the whole frame shear wall structure more stable.

Advantages and disadvantages of shear wall structure.

Advantages: 1) Good integrity;

2) The lateral stiffness is large, and the lateral displacement is small under the action of horizontal force;

3) Because there are no beams, columns, etc., which are exposed and protruding, it is convenient for the interior layout of the room.

Disadvantages: 1) Cannot provide a large space house;

2) Poor structural ductility.

Scope of application of shear wall structure: Due to the large ability to withstand vertical force and horizontal force, and the lateral stiffness is large, it can build buildings with higher and more floors than frame structures. However, houses that can only be used for small rooms, such as Sumichang-type houses, hotels, and single dormitories.

And in the hotel, you need a foyer with a large space. Restaurants, shopping malls, etc., are often set up in separate building units. Generally, it is suitable for use in the height range of 30m.

Remarks of Zhongda Consulting: How to choose the frame shear structure of the construction enterprise must be analyzed according to the basic situation of the project and select the appropriate project content.
