What are the structures of building construction projects

Brick concrete structure: It is supported by brick walls or blocks, and reinforced concrete floors, beams, and roofs work together. It is commonly used in residential buildings with less than 6 floors, and has low cost but poor seismic resistance and spatial flexibility.

Frame structure: The load-bearing skeleton is composed of reinforced concrete or steel beams and columns, and the walls are only enclosed and separated. It is suitable for multi story (≤ 15 stories) public or residential buildings, with flexible space but weak lateral stiffness.

Shear wall structure: relying entirely on reinforced concrete walls (especially elevator shafts, stairwells, etc.) to resist lateral forces, suitable for high-rise residential buildings (≤ 150m), with high stiffness and good seismic resistance, but limited spatial layout.

Frame shear wall structure (frame shear wall structure): The frame and shear wall work together, balancing spatial flexibility and lateral stiffness. It is commonly used in residential or public buildings with 10-30 floors.

Steel structure: All or the main load-bearing components are made of steel, with light weight, high strength, and fast construction. It is used for large-span (such as sports halls), super high-rise or industrial plants and requires anti-corrosion and fire prevention treatment.

Tube structure (including frame tube, tube in tube, bundle tube): A "tube" surrounded by dense column walls to resist lateral forces, suitable for super high-rise buildings (>30 floors).

Wooden structure: Traditional or modern laminated wood load-bearing, mostly used for low rise residential and landscape buildings, environmentally friendly but requires fire and corrosion prevention; Brick and wood structures belong to its subclass and are now rare.

Composite/hybrid structures: such as steel reinforced concrete (SRC) and steel reinforced concrete, combining the advantages of steel and concrete, used for landmark super high-rise buildings; The bottom frame masonry structure (bottom frame+upper masonry) is used for commercial and residential buildings and has weak seismic resistance.

Large span spatial structures, such as grid structures, mesh shells, suspension cables, and membrane structures, are used in sports venues, airports, etc., and do not rely on internal columns to achieve large spaces.
