The difference between multi-storey buildings and high-rise buildings

The difference between multi-storey buildings and high-rise buildings in China's General Principles for Civil Building Design (GB 50352—2005) divides residential buildings into low-rise buildings with one to three floors, multi-storey houses with four to six floors, medium-high-rise houses with seven to nine floors, and high-rise houses with ten floors or more. Except for residential buildings, civil buildings with a height of no more than 24m are single-storey and multi-storey buildings, and those with a height of more than 24m are high-rise buildings (except single-storey public buildings with a building height of more than 24m); Civil buildings with a building height greater than 100m are super high-rise buildings.

From an architectural point of view, a multi-storey building refers to a building whose height exceeds10m and is less than 24m (10m

According to the new "High Code", namely "Technical Specification for Concrete Structures of High-rise Buildings" (JGJ3-2002), reinforced concrete structures with 10 floors and 10 floors or more or with a height exceeding 28m are called high-rise building structures. When the building height exceeds 100m, it is called a super high-rise building.

According to the current regulations, more than ten floors are high-rise buildings.

The important difference between high-rise buildings and multi-storey buildings is that high-rise structures not only bear vertical loads, but also bear horizontal loads (such as wind and earthquake). For multi-storey buildings, the problem of horizontal load is not so prominent, while for high-rise buildings, the problem of horizontal load is more prominent. .

If the brick-concrete structure is too high, it is difficult to bear horizontal load. At this time, the reinforced concrete frame structure is adopted, and its ability to bear horizontal load is much higher than that of brick-concrete structure. However, no matter how high the building is, the reinforced concrete frame structure can hardly bear the horizontal load. At this time, reinforced concrete walls are added to the frame structure (called shear walls, which have strong ability to bear horizontal loads), or all reinforced concrete walls are used to bear larger horizontal loads.

In the structural design of high-rise buildings, not only vertical load but also horizontal load should be considered.

The difference between multi-storey houses and high-rise houses generally refers to buildings with six or seven floors, and high-rise houses refer to houses with six or seven floors or more. Multi-storey houses and high-rise houses have their own characteristics, so we can't simply say which one is better. We should consider the structure, cost, area, quality, room type, property management fees and so on. In terms of building quality, generally speaking, the construction standard and quality of high-rise residential buildings are higher than that of multi-storey residential buildings. Ordinary multi-storey houses are generally brick-concrete structures, while high-rise houses are cast-in-place reinforced concrete. The foundation is deep and solid, the wall is thick and impermeable, and the seismic performance is better than that of multi-storey houses, and the whole building will not sink and deform. High-rise residential buildings have wider horizons, better air quality and less noise; Because of the high building and strong natural wind, some rooms do not need air conditioning, which can save electricity. However, from the actual use area of houses, the housing acquisition rate of high-rise houses is lower than that of multi-storey houses, that is, houses with the same construction area are purchased, and the indoor construction area of high-rise houses is lower than that of multi-storey houses. The area of the house includes the usable area and common parts of the house, such as stairwells. Because there are elevators, elevator waiting rooms, basements and so on. In high-rise residential buildings, there are more public areas to be shared, so the actual occupancy rate is low. The property management of most high-rise residential buildings is relatively perfect, the residential environment is generally beautiful and comfortable, the management of parking bicycles and cars is good, and there are special people on duty at the elevator door and gate, so the residential area is relatively safe; However, the property management fee of high-rise residential buildings is higher than that of multi-storey residential buildings. High-rise residential buildings have elevators to go up and down stairs, which is convenient to get in and out. The elderly, the disabled and the sick can avoid the pain of climbing stairs. However, if the maintenance of the elevator is not in place, once the elevator fails, it will be more difficult for residents to go up and down the stairs. But from the perspective of room structure, multi-storey residential buildings are better than high-rise residential buildings. Due to structural reasons, generally, multi-storey residential buildings face south, and are ventilated from north to south, with large indoor use area, reasonable room type and easy separation and decoration. High-rise residential buildings generally adopt frame structure, and the location of several elevators should be considered, so the apartment design is a bit difficult.

The difference between high-rise buildings and multi-storey buildings is that multi-storey buildings generally refer to buildings with 6 or 7 floors, while high-rise buildings refer to buildings with 6 or 7 floors or more. Multi-storey houses and high-rise houses have their own characteristics, so we can't simply say which one is better. We should consider the structure, cost, area, quality, room type, property management fees and so on.

1. In terms of building quality, generally speaking, the construction standards and quality of high-rise buildings are higher than that of multi-storey buildings. Ordinary multi-storey houses are generally brick-concrete structures, while high-rise houses are cast-in-place reinforced concrete, with deep and solid foundation, thick walls, no water seepage and better seismic performance than multi-storey houses, so the whole building will not sink and deform; And the depreciation period is long.

2. High-rise buildings have broad vision, good air quality and low noise; The natural wind is strong, and some rooms can save electricity without air conditioning; Good lighting, long sunshine time, some facing the sun for seven or eight hours.

3. From the actual use area of the house, the housing acquisition rate of high-rise buildings is lower than that of multi-storey buildings, that is, the interior construction area of high-rise buildings is lower than that of multi-storey buildings. The area of the house includes the usable area and common parts of the house, such as stairwells. Because there are elevators, elevator waiting rooms, basements and so on. In high-rise residential buildings, there are more public areas to be shared, so the actual occupancy rate is low.

4. The property management of most high-rise buildings is relatively perfect, and the residential environment is generally beautiful and comfortable. Management of greening, landscape, sanitation, bicycle parking, cars, etc. It's good. There are special personnel on duty at the elevator door and gate, and the community is relatively safe; But the high-rise property management fee is higher than the multi-storey property management fee.

5. There is an elevator to go up and down the stairs, which is convenient to get in and out, so that the old, the weak and the sick can avoid climbing the stairs; However, if the elevator maintenance is not in place, once the elevator fails, it will be more difficult to go up and down the stairs.

6. Although the cost of high-rise buildings is high, high-rise buildings with the same building area occupy less land, so the price difference between high-rise buildings and multi-storey buildings is not big. The land price in the inner ring is relatively high, most of the new commercial houses are high-rise, and the residential quarters outside the inner ring are mainly multi-storey; In the inner ring road, sometimes the price of multi-storey buildings is higher than that of high-rise buildings.

7. From the perspective of room structure, multi-storey residence is better than high-rise residence. Due to structural reasons, generally, multi-storey residential buildings face south, and are ventilated from north to south, with large indoor use area, reasonable room type and easy separation and decoration. High-rise residential buildings generally adopt frame-shear wall structure, and the location of several elevators should be considered, so the design of apartment type is a bit difficult, and the decoration is easy to bring inconvenience.

What are the definitions and differences between multi-storey buildings and high-rise buildings? China's General Principles for Civil Building Design (GB 50352—2005) divides residential buildings into low-rise buildings with one to three floors, multi-storey buildings with four to six floors, medium-high-rise buildings with seven to nine floors, and high-rise buildings with ten floors or more. Except for residential buildings, civil buildings with a height of no more than 24m are single-storey and multi-storey buildings, and those with a height of more than 24m are high-rise buildings (except single-storey public buildings with a building height of more than 24m); Civil buildings with a building height greater than 100m are super high-rise buildings.

What are the main differences between high-rise buildings and multi-storey buildings? From an architectural point of view, a multi-storey building refers to a building whose height exceeds10m and is less than 24m (10m

According to the new "High Code", namely "Technical Specification for Concrete Structures of High-rise Buildings" (JGJ3-2002), reinforced concrete structures with 10 floors and 10 floors or more or with a height exceeding 28m are called high-rise building structures. When the building height exceeds 100m, it is called a super high-rise building.

Hello, how to distinguish multi-storey buildings from high-rise buildings? For residential buildings, floors 4 to 6 are multi-storey, floors 7 to 9 are middle and high-rise, and floors 9 and above are high-rise.

Is there a specific positional relationship between the distance between high-rise buildings and multi-storey buildings? Who is in the south and who is in the north? The relationship between their building and your location has an impact on the sunshine distance, and it will also have an impact if there is an angle.

If the requirements of the Ministry are too precise, you can multiply the sunshine spacing coefficient by their building height to get the distance from you. And even if the distance is enough, it should be counted as sunshine to see if it can meet the requirement of getting at least one hour of full window sunshine from winter to the bottom of the sun.

What is the sunshine coefficient of Huanggang?

The encyclopedia of sunshine spacing calculation, you can refer to:

:baike.baidu./view/533543。 ? wtp=tt

The distance between high-rise buildings and multi-storey buildings in Chongqing should be analyzed by sunshine. The proportion of each city is different. Basically, the building spacing should be above 1: 1.

For example, if a multi-storey building is in the south of a high-rise building, the distance between the two floors should be above the height of the multi-storey. On the contrary, if the high-rise building is in the south, the distance between the two floors should be above the height of the high-rise building. If it is a side-by-side building, only greening and municipal planning are considered.

For example, in Xi 'an, Shaanxi, the sunshine ratio is 1.3, that is, 1.3 times the height. Every city is different and its value is different, but it will not deviate too much.
