There are several ways to classify buildings.

According to the Code for Fire Protection Design of Buildings, there are many ways to classify buildings: industrial buildings include single-storey, multi-storey and high-rise workshops.

Warehouse, in which the fire risk categories are divided into A, B, C, D and E; Civil buildings include single-storey, multi-storey and high-rise residential buildings and public buildings, among which high-rise civil buildings are divided into one category and two categories. In the fire inspection, it is mainly to check the height, number of floors, fire risk and use nature of the building, so as to verify whether the building classification (including the fire risk classification of industrial buildings) meets the requirements of the current national technical standards for fire protection in engineering construction.

I. Classification by nature of use

(1) civil buildings. According to the use function and building height, the classification of civil buildings is shown in the table.

Note: Buildings not listed in the table should be determined by analogy in this table.

In the above table, residence refers to buildings where single people or family members live for a short or long time. Public buildings refer to buildings for people to carry out various public activities, including education, office, scientific research, culture, commerce, service, sports, medical care, transportation, memorial, gardens and comprehensive buildings.

(2) industrial buildings. Refers to industrial productive buildings such as main production workshops and auxiliary production workshops. Industrial buildings are divided into processing, production workshops and storage warehouses according to the nature of use, and workshops and warehouses are classified according to the nature of substances they produce or store.

(3) Agricultural architecture. Refers to the production buildings of agricultural and sideline industries, mainly including greenhouses, livestock farms, silkworm houses, flue-cured tobacco houses, granaries and so on.

Second, according to the classification of building structure

According to its structural form and building materials, it can be divided into wood structure, brick-wood structure, brick-reinforced concrete mixed structure (brick-concrete structure), reinforced concrete structure, steel structure, steel-reinforced concrete mixed structure (steel-concrete structure) and so on.

(1) wood structure. The main load-bearing component is wood.

(2) Brick and wood structure. The main load-bearing members are made of masonry and wood. Such as brick (stone) walls, wooden floors and wooden roofs.

(3) Brick-concrete structure. Vertical bearing members are brick walls or brick columns, and horizontal bearing members are reinforced concrete floors and roof slabs.

(4) Reinforced concrete structure. Reinforced concrete is the main load-bearing component of buildings such as columns, beams, floors and roofs, and is made of bricks or other lightweight materials.

Materials for walls and other housing parts. For example, buildings built by industrialized methods such as assembled large plates, large templates and slip forms, and buildings with reinforced concrete high-rise, long-span and large space structures.

(5) steel structure. The main load-bearing members are all made of steel. For example, a factory building built entirely of steel columns and steel roof trusses.

(6) Steel-concrete structure. The roof adopts steel structure, and other main load-bearing members adopt reinforced concrete structure. Such as reinforced concrete beams, columns and steel roof trusses.

(7) Other structures. Such as adobe buildings, plastic buildings and inflatable plastic buildings.

Three, according to the building height classification

According to the building height, it can be divided into two categories.

(1) Single-storey and multi-storey buildings. Residential buildings under 27m, public buildings and industrial buildings with a building height of less than 24m (or single-storey buildings with a building height of more than 24m).

(2) High-rise buildings. Residential buildings with a building height exceeding 27 meters and other non-single-storey buildings with a building height exceeding 24 meters. In China, high-rise buildings with a building height exceeding 100m are called super high-rise buildings.
