What materials are used for earthquake resistant houses?

1 Multi-storey masonry house. It is based on the seismic wall of masonry (unreinforced masonry or reinforced masonry) as the seismic structural system, in which the structural system based on the transverse wall bearing is more advantageous, the load-bearing transverse wall doubles as the transverse seismic wall, the longitudinal self-supporting wall is used as the longitudinal seismic wall, and the longitudinal and transverse wall mixed load-bearing can also be used if necessary.

2 multi-storey inner frame houses. It refers to the load-bearing house with brick wall buttress (or pilasters) on the outer wall and the load-bearing steel concrete column on the inner column, which is suitable for light factory buildings and civil public buildings that require a larger space in the process or a relatively empty hall in use.

3 Ground floor frame brick house. The ground floor requires a large space for shops, service halls, etc., and the upper part is a residential or office building with more partition walls, which is a structural system with different upper and lower materials, discontinuous strength and stiffness, and has stricter requirements in seismic design.

4 Frame structure. It is mostly used in multi-storey and high-rise civil buildings and multi-storey industrial buildings, with flexible building layout and easy to arrange large rooms. However, the lateral stiffness of the pure frame structure is small and it is a flexible structure, so its number of layers and height are limited to a certain extent.

5 Frame Seismic wall structure. Appropriate seismic walls are arranged longitudinally and transversely in the longitudinal and transverse directions of multi-storey and high-rise reinforced concrete houses, and a structural system that works in tandem with frame walls is formed with frame structures. Under the action of **, the interstory displacement is significantly reduced compared with the pure frame structure, so the building height can be much higher.

6 Seismic wall structure. It is a structural system composed of all longitudinal and horizontal seismic walls, which has good seismic performance and is widely used in high-rise residential buildings, apartments, hotels and other buildings.

The use of light steel structure to build a house, the seismic effect is good, the seismic level is above 8, the following is its seismic principle:

Generally speaking, the seismic performance of steel structure buildings is the best, because the steel structure is light, the force is equal to the acceleration of the mass, so the steel structure is small in the first force, especially the steel frame workshop with a lightweight roof panel, color steel plate maintenance wall of the steel structure in Wenchuan performance is very good, in the extreme earthquake area Beichuan County 3 steel frame workshops are slightly damaged and basically intact. In the entire earthquake area, most of these structures are basically intact, except for a few buildings whose maintenance walls have been damaged.

1. Steel structure.

The steel structure house is not only fast to build, compared with other building materials with the best seismic performance, but also the most strong, it is flexible, can absorb the best force, and can protect the lives and property of residents to the greatest extent.

2. Frame shear structure.

The seismic performance of a house with a frame plus shear wall structure is worse than that of a steel structure building, and if it is a house with a pure shear wall structure, the seismic resistance is slightly better.

3. Brick-concrete structure.

The multi-storey brick-concrete structure of the house has the worst earthquake resistance, if the ground floor is a frame structure, the top is a brick-concrete structure, then top-heavy, and it is most likely to collapse after the occurrence of **.

Housing structure and seismic resistance.

The houses we live in are different in structure due to the different heights, uses and construction times, and also determine the seismic resistance of the houses. So what kind of house is the most earthquake-resistant? Let's find out.

Seismic level of steel structure

Features: Steel structure is made of steel as the main structural material. Steel is characterized by high strength and light weight, and at the same time, due to the homogeneity and strength of the steel material, it can have large deformation, can withstand dynamic load well, and has good seismic resistance.

Application: However, due to the relatively high cost of steel structure buildings, the current application is not very common.

General super high-rise buildings (more than 100 meters) or buildings with large spans usually use steel structure, and the more typical steel structure buildings in Shenyang City are the shoes and hats shopping malls of the second phase of Wuai Market.

Seismic rating of shear wall structures

Features: The shear wall is to use reinforced concrete wall panels to bear the internal forces caused by various loads, and can effectively control the horizontal force of the structure.

Application: Shear wall structures are widely used in high-rise buildings (residential buildings with 10 floors or more or buildings with a height of more than 24 meters).

Seismic rating of frame structures

Features: The skeleton is composed of load-bearing beams and columns poured from reinforced concrete, and then assembled with hollow bricks or prefabricated aerated concrete, ceramsite and other lightweight plates as partition walls. The wall mainly plays the role of enclosure and isolation, and because the wall is not load-bearing, it can be made of various lightweight materials.

In the frame structure, there is also a kind of frame shear structure, also known as frame-shear wall structure, which is the combination of the two systems of frame structure and shear wall structure, which absorbs their respective advantages, which can not only provide a larger use space for the building plane layout, but also has good resistance performance. Housing of this structure has good earthquake resistance.

Application: Frame structures are more commonly used in modern architectural design, and most of the buildings we see are frame structures.

Seismic grade of brick-concrete structure

Features: "Brick" in brick-concrete structure refers to a building material of uniform size, including other sizes of special-shaped clay bricks, hollow bricks, etc. "Mixing" refers to the reinforced concrete ingredients prepared by steel bars, cement, sand and gravel and water in a certain proportion, including floor slabs, lintels, stairs and balconies.

These fittings are combined with load-bearing walls made of bricks, so they are called brick-concrete structures. Brick-concrete houses are generally multi-storey (less than 24 meters, less than 10 floors) houses, and their seismic performance is relatively weaker than the above three.

Application: Brick-concrete structure is generally used in multi-storey or span buildings, but due to the rigid pattern of brick-concrete structure of the house, the wall can not be changed, and in recent years, the frame structure and shear wall structure have been more and more commonly used, and the brick-concrete structure has rarely been applied in urban construction.

If the general rental house is made of reinforced concrete, it is better to make a frame structure, which is more earthquake-resistant, and the borehole structure is relatively poor, and it will collapse after a certificate.

Reinforced concrete structure: Steel structure is made of steel as the main structural material. Steel is characterized by high strength and light weight, and at the same time, due to the homogeneity and strength of the steel material, it can have large deformation, can withstand dynamic load well, and has good seismic resistance.

Shear wall structure: shear wall is to use reinforced concrete wall slab to bear the internal force caused by various loads, which can effectively control the horizontal force of the structure, and the structure that uses the shear wall to bear the vertical and horizontal force is called the shear wall knot.

Now in our country is prone to the occurrence of the most important places are studying and building earthquake-resistant houses, you can contact them, consult, this knowledge, I think the steel structure of the house is more earthquake-resistant, its closure using color steel plastic foam board, because he is light weight, high strength, will not fall off when the first comes, can effectively ensure the safety of people's bodies.

If we talk about the structure of the house, it must be that the frame-type reinforced concrete structure houses built now are more earthquake-resistant, and the old-fashioned wood-framed houses in the past are also more earthquake-resistant.

What kind of house is more earthquake-resistant? steel structure of the house. frame structure of the house. Such a house is more earthquake-resistant.

Generally speaking, wooden houses are more earthquake-resistant.

Houses are more earthquake-resistant, and if you want to live in a more earthquake-resistant house, you sit in a house that is all concrete, which is more earthquake-resistant.

What kind of house is more pit**, if you don't consider the comfort of living, of course, it is a grass house. The secondary is that the wooden house can also be pitted. Many Japanese people have wooden houses. Because they often ** over there.

This kind of brand is generally more influential.

The seismic standard of buildings is determined according to four factors: the type of building fortification, the type of structure, the intensity and the height of the building. Under normal circumstances, the seismic grade of the house is above level 7, and the fortification intensity is between 6-9 degrees, and the higher the fortification intensity, the stricter the requirements. At present, the seismic standards for new residential buildings are:

Small earthquakes are not bad (below level 5); Moderate earthquake repairable (below level 7); The earthquake does not collapse (level 7 or more).

Seismic standards for buildings:

1. Seismic grade.

The seismic grade of the house generally does not need to be divided, and the building structure is divided into four categories of earthquake resistance fortification, such as A, B, C, and D, and the general residential and office buildings are Class C buildings.

2. Intensity.

The ground disturbance attitude intensity is the empirical value of the seismic fortification and grouping of major cities and regions in China according to the geographical, geological and historical data, scientific exploration and verification, and is a regional concept.

The seismic fortification category is divided into Class A, B and D buildings, and the seismic fortification intensity of houses in most parts of the country is generally 8 degrees.

In anti-** houses, the most commonly used structure is the reinforced concrete frame structure.

An anti-** house is a kind of building designed to reduce the number of students in the event of an incident. This type of construction usually uses special structures and materials to improve its seismic performance. The design and construction of a resilient house requires consideration of several factors, such as the type of wave, the frequency and intensity of the waves, the height and quality of the building, and so on.

This type of structure enhances its strength and stiffness by adding steel and concrete to the frame of the constructed ingenious building. In addition, the bottom of the house is susceptible to impacts, so it is also important to strengthen the structure at the bottom. In some low-height buildings, masonry or timber structures can be used, but this requires reinforcement of the structure to improve its seismic performance.

In addition to the structure, building materials are also an important part of the design of a resilient house. The use of lightweight building materials can reduce the mass of the building, thereby reducing the force of inertia at **. At the same time, the use of certain special materials can also improve the seismic performance of the building.

For example, carbon fiber materials can be used to strengthen structures, while liquid dampers can be used to reduce vibrations when **.

In the event of an event, anti-housing can provide a safer refuge. These buildings are designed and built to reduce the destruction and collapse of buildings, thereby reducing personnel**. However, resistant homes are not completely immune to the damage caused, so after that, the building needs to be inspected and repaired.

In conclusion, anti-** houses are an important type of construction that requires special design and construction. There are several factors to consider for these buildings, including structure, materials, type, and more. By employing special structures and materials, resistant houses can provide safer shelter and reduce the damage caused.

Generally, the houses built by workers and civilians with reinforced concrete are 7 degrees fortified and 8 degrees checkedIndividual areas will be fortified at 8 degrees, as for whether it can be achieved, it is necessary to calculate before it can be concluded that the shear and bending resistance of the load-bearing wall and the shear wall can be determined not as good as that of the all-concrete structure, and the shear wall is mainly anti-load and wind load.

China's residential buildings are only calculated according to the seismic crack degree, and the highest is currently Beijing, with an eight-level crack resistance. Because the location and depth of the epicenter of ** cannot be estimated, it cannot be linked to the seismic intensity, for example, the epicenter is 5 kilometers directly below the house, and the relatively low ** will also cause serious consequences, if the epicenter is deep, it may resist a relatively large seismic intensity. Steel-concrete is definitely stronger than brick-concrete, because it is all cast-in-place concrete, the shear wall is stronger than the frame, and the tower is stronger than the slab building, which is probably what it means.

Whether it is a frame or a shear wall, the current specification must be resistant to 8 degrees of cracking, the reason why the shear wall is good is because it can better resist the edge effect, you know the ** shear wave and longitudinal wave,When the building sways from front to back, left and right, the gables on the top and edge will be subjected to the most swaying force, and the shear wall can resist better. The seismic crack resistance of the main structure of the building is not different from the draft, and this is not a comparison under the same parameters. Slow respect

How should buyers choose an earthquake-resistant house when buying a house? Look at the environment where the house is located: Is the surrounding environment where the house is located a protruding mouth, a towering mountain, or a steep slope that is not rocky?

Whether there are liquefiable layers of saturated sand and sub-clay within 15 metres below the surface. Generally located in the above locations are more susceptible to the influence of **.
