Brick and wood structure building

1. Brick and wood structure building: The main load-bearing components of this type of building are made of brick and wood. The walls and columns of the vertical load-bearing components are made of brick, while the floors and roof trusses of the horizontal load-bearing components are made of wood. The number of floors in this type of building is generally low, usually below 3 floors. Ancient architecture and buildings from the 1950s and 1960s often have this type of structure. 2. Brick concrete structure building: The vertical load-bearing components of this type of building use brick walls or brick columns, and the horizontal load-bearing components use reinforced concrete floors and roof slabs, including a small number of roofs using wooden frames. The number of floors of this type of building is generally below 6, with low cost and poor seismic resistance. The width, depth, and floor height are all limited. 3. Reinforced concrete structure building: The load-bearing components of this type of building, such as beams, slabs, columns, walls, roof trusses, etc., are composed of two major materials: steel bars and concrete. Its enclosure components such as walls and partitions are made of lightweight bricks or other masonry. The characteristics are strong structural adaptability, good seismic resistance, and durability. The types of reinforced concrete structure houses include frame structure, frame shear wall structure, shear wall structure, simplified structure, frame tube structure, and tube in tube structure. 4. Steel structure building: The main load-bearing components of this type of building are all made of steel, which has high construction costs and is often used in multi-story public buildings or buildings with large spans. [1] （4） The classification of construction methods by building construction method refers to the methods used in building construction. Cast-in-place masonry building: The main load-bearing components of this type of building are all cast and built at the construction site. Prefabricated and prefabricated building: the main load-bearing components of such buildings are prefabricated components made in the processing plant and assembled at the construction site. Partial cast-in-place and cast-in-place masonry, partial prefabricated building: some components (such as walls) of such buildings are poured or built on the construction site, and some components (such as floors and stairs) are prefabricated components made in the processing plant.

Classification by nature of use

Residential buildings: refer to buildings designed for families or individuals to reside for a long period of time, and can be divided into residential and collective dormitories (residential buildings are divided into ordinary residential, high-end apartments, and villas; collective dormitories are divided into single employee dormitories and student dormitories). Public buildings refer to non productive buildings used by people for shopping, office, learning, medical treatment, travel, sports, etc., such as office buildings, shops, hotels, cinemas, gyms, exhibition halls, hospitals, etc. Industrial buildings: refer to buildings used for industrial production or directly serving industrial production, such as factories, warehouses, etc. Agricultural buildings: refer to buildings used for agricultural production or directly serving agricultural production, such as silos, breeding farms, etc. [1] （2） The number of floors of a house classified by floor number or total height refers to the natural number of floors of the house, generally calculated based on an indoor floor level of ± 0 or above; For a semi basement with daylight windows above the outdoor floor level, if the indoor floor height is above 2.20m (excluding 2.20m), the natural number of floors shall be calculated. False floors, attached floors (mezzanine), insertions, attics, decorative towers, as well as stairwells and water tank rooms protruding from the roof, do not count the number of floors. The total number of floors in a house is the sum of the number of floors above ground and underground. Residential buildings are divided into low-rise residential buildings (1-3 floors), multi-story residential buildings (4-6 floors), medium to high-rise residential buildings (7-9 floors), and high-rise residential buildings (10 floors and above) based on the number of floors. Public buildings and comprehensive buildings with a total height exceeding 24m are high-rise buildings, but do not include single story buildings with a total height exceeding 24m. A building with a total height exceeding OOm, whether it is a residential or public building, or a comprehensive building, is called a super high-rise building [1] （3） According to the classification of building structure, building structure refers to the system composed of load-bearing components (foundations, walls, columns, beams, floors, roof trusses, etc.) in a building.
