Classification and advantages of multi-storey steel structure buildings

A multi-storey building is a three-dimensional or light steel structure building with a number of storeys containing vertical circulation via elevators and stairs. Based on preliminary analysis and validation, a wide range of methods have been adopted for these buildings of different heights. Multi-storey buildings are generally designed to be used as hospitals, commercial malls or apartments.

As the ideal solution for commercial buildings, multi-storey buildings can be built faster than other traditional buildings due to the use of a high level of material prefabrication, design precision, optimal quality checks and risk-free construction.

First, the classification of multi-storey steel structure buildings:

Based on their height, usage needs, and various other factors, we can divide multi-storey buildings into the following categories

1. Low-rise building: This type of low-rise multi-story building usually has fewer floors (usually less than four floors), and vertical transportation is mainly through elevators and stairs.

2. Mid-rise building: The number of floors in a mid-rise building is between 4 and 12.

3. High-rise buildings: The number of floors in high-rise buildings varies from 12 to 40 floors, and vertical traffic is also carried out by elevators and stairs.

4. skyscraper: If the height of a tall livable steel structure building of more than 40 floors is less than 300 meters, then it can be considered a skyscraper style multi-storey building.

5. super high-rise buildings: super high-rise buildings refer to those steel structure buildings with a height of more than 300 meters, they belong to the category of super high-rise multi-storey buildings.

6. super tall buildings: super tall buildings refer to those steel structure buildings with a height of more than 600 meters, they also belong to the category of super tall multi-storey buildings.

Second, the advantages of multi-storey buildings:

Cost-effectiveness: During construction, the cost of labor and equipment used in multi-story buildings is usually lower than that of other conventional buildings.

Light weight: Through the use of lightweight slabs and steel, the floor weight of multi-storey steel buildings is very light, which makes these buildings look more dramatic and makes their overall weight lighter than other traditional buildings.

Design freedom: A key feature of multi-storey buildings is the freedom in their geometry, which makes them more innovative in design than other traditional buildings.

Construction mechanization: Since steel is not only a building material, but also has technical strength, the steel components used for the installation of multi-storey buildings are made with mechanization practices and high-precision software to achieve construction accuracy.

Fire safety: These buildings are designed and constructed to include adequate fire safety provisions to avoid threats to life.

Natural light and ventilation: Adequate natural light and good ventilation can improve people's work efficiency. The multi-storey building provides excellent conditions for natural light and ventilation.

Strong structure: Multi-storey PEB buildings are designed to meet the needs of a strong structure and even exhibit excellent seismic performance.
