What is the difference between frame structure, frame shear structure and shear wall structure? How

The difference and method of frame structure, frame shear structure and shear wall structure are as follows:

Frame-shear wall structure, known as frame shear structure, is a combination of frame structure and shear wall structure, which draws on their respective advantages, which can not only provide a large use space for the building plane layout, but also have good lateral force resistance. The shear wall in the frame shear structure can be set separately, or it can use walls such as elevator shafts, stairwells, and pipe shafts. Therefore, this structure has been widely used in all kinds of housing construction.

The deformation of the frame shear structure is a shear-curved type. As we all know, the deformation of the frame structure is shear-type, the relative deformation between the upper layers is small, and the relative deformation between the lower layers is large. The deformation of the shear wall structure is curved, and the relative deformation between the upper layers is large, and the relative deformation between the lower layers is small.

For the frame-shear structure, due to the coordinated deformation and coordination of the two structures, the bending and shear deformation is formed, which reduces the relative displacement ratio between the layers and the displacement ratio of the vertex, and improves the lateral stiffness of the structure.

The horizontal load is mainly borne by the shear wall. From the perspective of force characteristics, because the lateral stiffness of the shear wall in the frame shear structure is much larger than the lateral stiffness of the frame, under the action of horizontal load, under normal circumstances, more than 80% of the shear wall is borne by the shear wall. Therefore, the floor shear force distributed by the frame structure under the action of horizontal load is evenly distributed along the height, and the bending moment of each layer of beams and columns is relatively close, which is conducive to reducing the specifications of beams and columns, and is convenient for construction.

Which is good is only relative, there is no absolute, and it is best to choose according to the actual situation.

(1) Brick-concrete structure.

It is made of bricks or load-bearing blocks.

construction of load-bearing walls, cast-in-place or prefabricated reinforced concrete.

A building structure composed of floor slabs. It is mostly used to build low-rise or multi-storey residential buildings.

2) Frame structure.

The main skeleton load-bearing structure composed of beams and columns, the floor slab is generally cast-in-place concrete, and the wall is infill wall. It is mostly used to build medium and high-rise buildings.

3) Frame a shear wall structure.

It is a structure that bears both vertical and horizontal action by a shear wall and a frame, which is also called a frame seismic wall.

Structure. The difference between frame seismic wall structure and frame structure is to increase the stiffness and integrity of the building, turning a part of the infill wall that is not stressed in the frame structure into a reinforced concrete wall that bears wind and ** horizontal loads. Mostly used to build.

Construction of mid-rise and high-rise buildings.

4) Shear wall structure: It is a structure composed of shear wall to withstand vertical and horizontal force, also called seismic wall structure. The walls and floor slabs of the shear wall structure that are subjected to vertical and horizontal loads are all cast-in-situ reinforced concrete. It is mostly used to build medium and high-rise buildings.

5) Steel structure: beams, columns, and floor slabs are all steel, and the wall is composed of thin metal plates filled with lightweight insulation materials. Therefore, it is light and can be used to build super high-rise buildings.

6) Light steel structure: The beams, columns, and roof trusses of the building are composed of highly simplified steel components, and the construction speed is fast, which is suitable for building low-rise and multi-storey industrial and civil buildings.

There are many areas of expertise in complex construction projects that we don't understand, let alone understand. But when it comes to frame-shear wall structures, I believe that fewer people know about them, but in fact, they are in our high-rise buildings.

There are many areas of expertise in complex construction projects that we don't understand, let alone understand. But when it comes to frame-shear wall structure, I believe that few people know about it, but it is actually common in our high-rise buildings. But after all, we are not professionals.

How is it possible for us to understand this expertise? So next, let's take a good look at the characteristics of the frame-shear wall structure.

1.What is a frame shear wall structure.

First of all, we need to understand the framework structure.

In fact, it refers to the structure of a load-bearing system, which is composed of beams and columns connected in a rigid or hinged way, that is, the frame composed of beams and columns resists horizontal and vertical loads together in use. In fact, the structural walls of the house.

It is not load-bearing, but only plays the role of enclosure and separation. In fact, shear walls are also called wind-resistant walls.

Or earthquake-resistant walls.

Their main role is to bear the wind load or horizontal load caused by ** in the construction of the house to prevent the structure from being damaged by shear, but they are generally made of reinforced concrete.

and cast-in-place reinforced concrete. In fact, the structure of the frame-shear wall will also be referred to as the frame-shear wall structure. Literally, it can be understood that a certain number of shear walls are arranged in the frame structure, which constitutes a very flexible and free use space.

The stress characteristic is a form of stress consisting of two different lateral force resistant structures, the frame and the shear wall. The interaction between the frame and the shear wall makes the entire frame-shear wall structure more stable.

2. What are the characteristics of the frame shear wall structure?

The main feature of shear walls is that they can withstand both vertical and horizontal loads. In the shear wall structure, the wall and the floor form a stress system, but its disadvantage is that the shear wall cannot be removed or destroyed, which is not conducive to the formation of a large space, and residents will not be able to transform the interior layout by themselves. The application of short-limb shear wall structure is becoming more and more extensive, and it adopts a shear wall with a smaller width.

Residents can modify the interior layout to a certain extent to increase its flexibility, but this is to reduce the mechanical properties of the entire structure.

at the expense. Well, the above is the knowledge that Bian Xiao has compiled for you about the characteristics of the frame-shear wall structure. I believe that everyone now knows the characteristics of frame-shear wall structure, because this type of structure is very professional, so professionals must design and construct it when constructing.

When most families buy a house, they don't know much about the structure of the house, and the construction of the house is also a more complicated process.

1. What are the differences between frame structure and shear wall 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 use space for the building, suitable for large-scale industrial construction, with high efficiency and good engineering quality. It is often used in multi-storey public buildings with less than 10 floors, such as buildings, shopping malls, etc., and is also used in high-rise buildings in non-** areas.

Advantages: indoor, can meet complex building forms, slightly stronger seismic resistance. The partition wall of the room can be demolished and modified at will.

Disadvantages: The frame column size is too large, which is not suitable for civil housing. It is difficult to go beyond 7 floors in the ** area.

Shear walls, more accurately named "structural walls". Refers to the wall that resists the horizontal shear force added in the frame structure, which 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. When the walls are in the right position in the building, they can form a structural system that effectively resists horizontal action, and at the same time, they can play a role in dividing the space.

The height of the shear wall is generally equal to the height of the whole house, from the foundation to the roof, up to tens of meters or more than 100 meters; Its width depends on the layout of the building plane, generally a few meters to more than ten meters. Comparatively speaking, its thickness is very thin, generally only 200 300mm, and the small can be up to 160mm. Therefore, the anti-lateral stiffness of the shear wall in the plane of the wall is very large, while the stiffness of the wall outside the plane is very small, which can generally be ignored Huki.

As a result, most of the horizontal action or horizontal shear forces on the building are usually distributed to the structural walls. It is often used in ordinary high-rise residences, and multi-storey bungalows and villas with complex room types. The load-bearing structure is a sheet of concrete walls, and the rooms do not have the edges and corners of the columns, which is more suitable for residential use than frame structures.

The concrete walls are highly resistant to earthquakes and the safety of the house is very high. The amount of concrete is large, and the total height usually cannot exceed 150m. The concrete wall is a high-strength load-bearing wall, and the room cannot be demolished.

2. How to distinguish between frame structure and shear wall structure?

The distinction between shear wall structure and frame structure is mainly to see whether the structure contains shear wall. The shear wall structure is good as a structure, but its cost is too large, and the frame structure is not enough to stress it, so the general building is mostly a frame shear structure.

Buying a house is an important thing, and it is also important to understand the structure of the house, so do you know how the frame structure and the shear wall structure are? What are the differences between frame structures and shear wall structures? The following is an introduction to the relevant information of frame structure and shear wall structure!

Introduction to frame structures and shear wall structures

Shear wall, also known as wind-resistant wall or earthquake wall, the primary effect is to accept the horizontal load caused by the wind load or ** effect in the construction of the house to prevent structural shear damage, divided into plane shear wall and three-dimensional shear wall, generally built with reinforced concrete and cast-in-place reinforced concrete.

Structural structure refers to the structure composed of beams and columns connected by rigid or hinged joints to form a load-bearing system, that is, the structure composed of beams and columns resists the horizontal and vertical loads presented in the process of application. The walls of the constructed house are not load-bearing, but only serve as an enclosure and separation.

Structural structures are often used in high-rise buildings, shopping malls, and hotels with some concrete walls, called structural shear wall constructions.

Strengths: The use of interior space and the demolition and modification of room partition walls are as sensitive and changeable as the structure. The seismic performance is the same as that of a pure shear wall structure. Defects: The amount of concrete is large, the dead weight is large, and the total height generally cannot exceed 150m.

Shear wall structures can be built with a higher and higher number of floors than structural structures. However, it can only be a house with small rooms, such as a residence, a hotel, and a single dormitory. And the foyer in the hotel needs a large space. Restaurants, shopping malls, etc., are usually set up in other building units.

The difference between a structural construction and a shear wall construction

The deformation of the frame shear structure is the shear-bend type. As we all know, the deformation of tectonic structure is shear, with small relative deformation between upper layers and large relative deformation between lower layers. The deformation of the shear wall structure is zigzag, with large relative deformation between upper layers and small relative deformation between lower layers.

For the frame shear structure, because the two structures work together to deform harmoniously, the bending and shear deformation is formed, and then the relative displacement ratio between the layers and the displacement ratio of the pole is reduced, so that the lateral stiffness of the structure is improved.

The horizontal load is primarily accepted by the shear wall. From the point of view of stress characteristics, because the lateral stiffness of the shear wall in the frame shear structure is much larger than the lateral stiffness of the structure, therefore, the floor shear force distributed by the structural structure under the effect of horizontal load is evenly distributed along the height, and the bending moment of each layer of beams and columns is close to each other, which is conducive to reducing the beam and column standard and is convenient for construction.

The above is the relevant information about the frame structure and the shear wall structure, in the above I introduced the relevant information about the difference between the frame structure and the shear wall structure, I hope it will be helpful for you to understand the frame structure and the shear wall structure when choosing a house!

What is the difference between a frame and a shear wall structure?

1. Different stress systems: the frame structure is a structural system formed by using the vertical and horizontal frames composed of beams and columns, which bear both vertical and horizontal loads. The shear wall system is to use the wall of the building (inner wall or outer wall) to make a shear wall to resist the horizontal force, and at the same time it also bears the vertical load, so it is subject to both shear force and bending, so it is called a shear wall.

2. Respective advantages: The main advantage of the frame structure is that the building layout is flexible, which can form a larger building space, and the building façade treatment is also more convenient. The advantages of the shear wall structure are that the lateral stiffness is large, and the lateral displacement is small under the action of horizontal load.

3. Their respective disadvantages: the lateral stiffness of the frame structure is small, and when the number of layers is large, it will produce a large lateral shift, which is easy to cause the destruction of non-structural components (such as partition walls, decorations, etc.) and affect the use. The spacing of the shear wall structure is small, the plane layout of the structure building is not flexible, and it is not suitable for public buildings with large space, and the self-weight of the structure is also large.

Fourth, the height of the building to adapt to the erection of the reed: the frame structure is in the non-** area, generally not more than 15 floors. Shear walls are generally suitable in the 30m height range.

From the above comparison, we can find that the advantages and disadvantages of the two are complementary, so another structural fiber liquid type is produced, that is, the so-called "frame shear wall structure", which is a structural system in which an appropriate shear wall is set in the frame structure. It has the advantages of flexible plane layout and large space of frame structure, and has the advantages of large lateral stiffness. It is a combination of the best of both.

In this structural system, the shear wall is mainly subjected to horizontal loads, and the vertical loads are mainly borne by the frame. This structure is generally suitable for buildings with 10 or 20 floors.
