Advantages and disadvantages of frame structure, what are the advantages of frame structure building

The main advantages of frame construction:

The space separation is flexible and the weight is light, which is conducive to earthquake resistance and material saving; It has the advantage of being able to flexibly match the layout of the building, which is conducive to arranging the building structure that requires a larger space.

The beams and columns of the frame structure are easy to be standardized and stereotyped, and the integral structure of assembly is convenient to be adopted to shorten the construction period; When the cast-in-place concrete frame is adopted, the integrity and stiffness of the structure are better, and the design treatment can also achieve better seismic effect, and the beam or column can be poured into various required cross-sectional shapes.

Frame structure system.

The disadvantage is: the stress concentration of the frame joint.

Significant; The lateral stiffness of the frame structure is small, it is a flexible structural frame, and under the strong action, the horizontal displacement of the structure is large, which is easy to cause serious non-structural breakage; The amount of steel and cement is large, the total number of components is large, the number of hoisting is large, the joint workload is large, the process is many, the manpower is wasted, and the construction is greatly affected by the season and the environment; It is not suitable for high-rise buildings.

The frame is a rod structure composed of beams and columns, and its bearing capacity and stiffness are low, especially in the horizontal direction (even if the cast-in-place floor and the beam can be considered to work together to improve the horizontal stiffness of the floor, but it is also limited), its stress characteristics are similar to the vertical cantilever shear beam, its overall horizontal displacement is large and small, but relative to each floor, the interstory deformation is small and large, how to improve the lateral stiffness of the frame and control the structural lateral movement is an important factor in the design, for reinforced concrete.

Frame, when the height is large and the number of layers is quite large, not only the axial force of the columns at the bottom of the structure is large, but also the bending moment of the beams and columns caused by the horizontal load.

And the overall lateral displacement also increases significantly, resulting in the increase of cross-sectional size and reinforcement, the building layout and space processing, it may bring difficulties, affect the rational use of building space, in terms of material consumption and cost, also tend to be unreasonable, so it is generally suitable for the construction of houses with no more than 15 floors.

Advantages: 1) Light weight: the weight of the brick-concrete structure is 1500 kg square meters; The self-weight of the frame structure such as the use of light plate (aerated concrete partition wall, light steel keel partition wall, etc.) is 400 kg 600 kg square meters, which is only 1 3 of the brick-concrete structure.

2) Flexible room layout: The load-bearing structure of the frame structure is the frame itself, and the wall panel only plays the role of enclosure and separation, so the layout is more flexible.

3) Increase the effective area: the frame structure wall is thinner than the brick-concrete structure, which relatively increases the usable area of the house.

Disadvantages: 1) The amount of steel is about 30% higher than that of brick-concrete structure, and the cost is higher than that of brick-concrete structure.

2) The cross-sectional size of some columns is too large, which will protrude out of the wall and affect the appearance.

First, the advantages of the frame structure

1. If the frame structure is adopted, the weight itself is relatively light, and the length of the building layout can be effectively used during construction, and a larger space can be obtained at the same time.

2. When the house with this frame structure is poured, the integrity and strength are relatively good, if the planning is reasonable, it can achieve a good seismic effect, and strong seismic resistance is one of its biggest highlights.

3. As long as the construction is reasonable and the quality of the project is ensured, it can meet the needs of fire protection. In addition, in the whole construction process, the construction period can be greatly shortened, and the cost can be effectively reduced.

Second, the shortcomings of the frame structure

1. The side stiffness of the frame structure is still relatively small, and if a strong ** occurs, such as reaching the above level, it may lead to serious damage to the non-structure.

2. In the process of construction, bricks need to be hung, and the number of times is relatively large, and it will be affected by the construction environment.

3. This frame structure is not suitable for high-rise buildings.

The higher the house is built, the lower its bearing capacity and stiffness, so it is not recommended to build a house with more than 15 floors.

What are the advantages and disadvantages of frame structure construction?

Advantages: 1. It has the advantages of being able to flexibly match the layout of the building, which is conducive to arranging the building structure that requires a larger space, and the beams and columns of the frame structure are easy to be standardized and stereotyped, and it is convenient to adopt the assembly integral structure to shorten the construction period.

2. When the cast-in-place concrete frame is adopted, the integrity and stiffness of the structure are good, and the design and treatment can also achieve a better seismic effect, and the beam or column can be poured into various required cross-sectional shapes.

Disadvantages: 1. The stress concentration of the frame joint is significant, the lateral stiffness of the frame structure is small, and it is a flexible structural frame.

2. There are many times of hoisting, large workload of joints, many processes, waste of manpower, and the construction is greatly affected by the season and environment; It is not suitable for the construction of high-rise buildings, and the frame is a rod structure composed of beams and columns, which has low bearing capacity and stiffness.

Extended information: 1. Attention should be paid to concrete design: the longitudinal reinforcement ratio should not be greater than 5. When the longitudinal reinforcement ratio is greater than 3, there are requirements for stirrup diameter, spacing and hook, and it can also be welded into a closed ring type, and the seismic design should not be greater than 5

2. Beam: The main beam should not be left with a facility joint; The construction joint of the secondary beam should be left at the third division point of the secondary beam span. The cantilever member should be poured as a whole to the structure to which it is connected.

3. Column: The construction joint should be left 30mm below the elevation of the bottom of the beam or at the elevation of the beam and plate surface.

4. Wall: The construction joint should be left at the third division point of the span of the lintel at the door opening, and can also be left at the junction of the vertical and horizontal walls.

Advantages of frame construction.

1. The space separation is sensitive, and the weight is light, which is conducive to earthquake resistance and material saving; It has the advantage of being able to arrange the building plan more sensitively, and is conducive to organizing the building structure that requires a large space;

2. When the cast-in-place concrete frame is selected, the integrity and stiffness of the structure are good, and the planning and treatment can also achieve a better seismic effect, and the beam or column can be poured into a cross-sectional shape of various needs.

3. Strong seismic resistance is the biggest feature of the frame structure. Because the integrity and stiffness of the structure are good, the joint part can resolve the infinite torsion that occurs, and the planned frame structure can also achieve a better seismic effect.

4. The beams and column components are easy to be standardized and stereotyped, which can meet the requirements of civil air defense and fire protection, so that the layout of water, electricity and heating can be carried out effectively, which can greatly shorten the construction period and reduce expenses.

2) Shortcomings of the frame structure.

1. The lateral stiffness of the frame structure is small, it is a flexible structural frame, and under the strong action, the horizontal displacement of the structure is large, which is easy to cause serious non-structural damage;

2. There are many times of hoisting, large workload of joints, many processes, waste of manpower, and the construction is greatly affected by the season and environment;

3.

4. It brings difficulties to the layout and space processing of the building, affects the rational use of the building space, and tends to be unreasonable in terms of material consumption and cost, so it is generally suitable for the construction of houses with no more than 15 floors.

Second, the difference between brick-concrete structure and frame structure.

1. Different load-bearing methods: the load-bearing structure of brick-concrete structure is composed of slabs and walls, and the frame structure is a load-bearing structure composed of floor slabs, beams and columns.

2. The system is different: the brick-concrete structure is a mixed structural system composed of reinforced concrete beams, columns, slabs and other components, and the frame structure is composed of frame columns.

3. Different structures: the stiffness and strength of the frame structure system are relatively good, it is a flexible structure, the masonry itself is composed of brittle materials, the tensile and shear strength is relatively poor, the ductility is also very poor, the anti-deformation ability is small, it is easy to cause damage to the structure, and it is a rigid structure.

4. The floor height is different: the brick-concrete structure can achieve up to 6 floors, while the frame structure can achieve 30 floors.

In comparison with each other, the frame structure is better than the brick-concrete structure in terms of earthquake resistance, stability, and toughness, and the frame structure has a large space, which can change the size of the room and is not easy to break the ring.

The main advantages of frame construction:

Scope of application of frame structure:

It is not suitable for the construction of high-rise buildings, and is generally suitable for the construction of houses with no more than 15 floors.

The main advantages of frame architecture: flexible space separation, light weight, and material saving; It has the advantage of being able to flexibly match the layout of the building, which is conducive to arranging the building structure that requires a larger space. The beams and columns of the frame structure are easy to be standardized and stereotyped, and the integral structure of assembly is convenient to be adopted to shorten the construction period; When the cast-in-place concrete frame is adopted, the integrity and stiffness of the structure are better, and the design treatment can also achieve a better seismic effect, and the beam or column can be poured into various required cross-sectional shapes.

1.It has the advantage that it can be more flexibly matched with the plane layout of the building, which is conducive to arranging the building structure that needs space, and the beams and column components of the frame structure are easy to be standardized and stereotyped, so as to facilitate the use of assembling the integral structure, so as to shorten the construction period.

2.When the cast-in-place concrete frame is adopted, the integrity and stiffness of the structure are better, and the design treatment can also achieve a better seismic effect, and the beam or column can be poured into various required cross-sectional shapes.

The advantage of the frame structure is that the seismic performance is particularly strong, and the space separation is more flexible, and the standard degree of construction is relatively high, and its structural integrity is also better, and its components are also more convenient to shape. Moreover, it is also very convenient when assembling, and the overall construction period can be compressed, and the weight is relatively light, and it will not cost materials.

The use of frame structure for design, its construction time is relatively short, and can reduce a certain amount of construction costs. Whether it is a building or a self-built house, the frame structure must be built before construction can begin.

Hello, the advantages of frame structure buildings are: flexible space division, conducive to earthquake resistance, light weight, saving materials, etc.

The frame structure of the building is good seismic resistance, the floor layered load is good, and the zero life application is good.

The structure is integrated and has strong seismic resistance. Large space and flexible segmentation. The integrity of the mechanism is good, the degree of construction standardization is high, and it is easy to assemble. The weight is light, the material is saved, and the construction period is relatively shortened.

1. The cost is relatively cheap, the force transmission is relatively clear, and the calculation is relatively simple.

2. The space layout is flexible and open.

3. It is convenient to transform in the future.

The construction of the frame structure is conducive to the sealing of **. And the period of building a house will be shortened. There are many advantages of frame structure.

First supported by the frame, the outline of the building and the driving and supporting points of the building. The outline of the building and the general idea of the building have already risen, and the rest can be connected with bricks so that it is particularly stable, special fast, and especially safe, as long as you don't cut corners.

This type of building is strong and does not collapse easily.

Multi, high-rise buildings.

There are the following structural systems:1Frame structure.

2.Shear wall structure.

3.Frame-shear wall structure 4Frame-cylinder structure 5Frame tube structure 6Cylinder-in-cylinder structure 7Multi-barrel structure 8Suspension structure 9Giant frame structure 10Giant truss structure.

11.Rigid beams or rigid truss structures.

The advantages and disadvantages of the frame structure are as follows: Advantages 1Space big 2

Good ductility 3The cost is slightly lower. Cons 1

The bearing capacity is low by 2Low stiffness (flexible structure) 3Side shift is larger than 4

The damage of non-structural components is heavy, and the maintenance cost is high5The secondary is complex on the inside6Lack of a second line of defense 7

Buildings with 8 floors in the earthquake zone should not be used, and the effect is significant. It should be pointed out that among the shortcomings of the frame structure, the fatal disadvantage is the lack of a second line of defense, which will significantly reduce the seismic resistance of the structure. Therefore, more attention should be paid to the selection of structures.

The advantages of shear wall structure are large lateral stiffness and small deformation, so there is less damage to non-structural components, and secondary disasters such as water outage, power outage, and fire are missing.

Small. The secondary internal forces and p- effect of the structure are not significant, and the problems of elastoplastic stability are not prominent. After reasonable design and appropriate component measures, ductility can meet the requirements of the specification, even if the wall is seriously cracked and the strength is attenuated, its bearing capacity is rarely reduced to below the critical bearing capacity required for load-bearing, so the seismic capacity is strong, the seismic damage is light, and there are only a few collapses.

The disadvantage is that the plane layout is not flexible enough, the large room is limited, the structure is self-weighted, the stiffness is large, the cycle is short, and the force is large, and the method of adjusting the stiffness can be used to reduce the above shortcomings.

Advantages of frame-shear wall structure 1Small side shift (compared to the same frame) 2Reduce the burden on the node3

Increase the number of times of superstatic stating by 4Ensure the uniform development of the plastic hinge 5The lateral shift between the layers tends to be uniform6

The shear force of each layer of the frame part tends to be uniform. The disadvantage is that the horizontal stiffness is uneven.

Advantages of cylinder structure 1The bearing capacity is high by 2The spatial stiffness is large 3

Good seismic and wind resistance4It is suitable for high-rise buildings with more than 20 floors and many floors. Cons 1

The amount of calculation is large, and it must be calculated 2Computationally complex 3The construction is difficult.
