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

1, difference between floors and building quality: floors refer to buildings with 4-6 floors, most of which are higher than10m and lower than 24m. The number of high-rise floors refers to buildings with more than 12 floors. In addition, multi-storey buildings generally adopt brick-concrete structure, while high-rise buildings adopt steel-concrete structure. From the perspective of architectural structure, high-rise buildings have better strength, stronger walls, seismic performance and architectural appearance than multi-storey buildings.

2. Comfort difference: the plot ratio of multi-storey buildings is 0.8- 1.2, and that of high-rise buildings is between 1.5-4.5. The smaller the volume, the better the building environment and the greater the comfort. In addition to the architectural environment, the multi-storey building is transparent from north to south, with good lighting, and the high-rise building will be equipped with elevators and other equipment, which is convenient. Moreover, due to the high floors and low noise of high-rise buildings, in addition to the north-south permeability of the apartment, there can be more balcony and roof planning areas.

3. Difference of pool area: There are few multi-storey high-rise buildings with plot ratio, because the multi-storey buildings are not equipped with elevators and other equipment, so the pool area is smaller than that of high-rise buildings.

4. The difference of property fees: the standard of multi-storey property is generally cheaper than that of high-rise buildings, while the maintenance, annual inspection and secondary water supply of high-rise buildings and elevators cause high property fees.

5. Different decoration methods: multi-storey buildings will face south, with large indoor use area and reasonable apartment layout, which is easier to design when decorating. However, the structure of high-rise buildings is complex and the indoor units are often cramped, which brings inconvenience to the decoration design.

What is a multi-storey house?

1. Multi-storey residence means that the building height is greater than10m and less than 24m (10m2). The overall stiffness and seismic performance of multi-storey residential superstructure are very important, and the corresponding foundation selection has also become an important factor affecting structural safety and building economy. Through a large number of engineering practices, it is found that some buildings are not suitable for superstructure in foundation selection, and are not in harmony with foundation conditions, and cannot closely cooperate with foundation, foundation and superstructure in space to play a greater and more full role.

3. Some buildings ignore the superstructure when choosing the foundation, and do not consider the foundation conditions of the construction site well. The foundation was designed in isolation, and some problems appeared after it was built and used. Therefore, it is very necessary to sum up experience carefully, choose the foundation form correctly and guide the engineering design. In view of this problem, this paper analyzes the specific application of multi-storey residential foundation selection.

How many floors or more does a high-rise residence mean?

High-rise residence refers to the residence above 10 floor. Compared with multi-storey residential buildings, the layout of high-rise residential buildings is basically the same, except for an elevator. Therefore, it has good ventilation, lighting and ornamental effects and good indoor layout. Moreover, the shared public area of each household is not large.
