1. Wood structure: the walls and columns of the vertical load-bearing structure in the building are built with bricks or blocks, and the floors and roof trusses are built with wood structures. Generally made of reinforced concrete. Use precast reinforced concrete thin beams to mix second class and others to mix first class.
2. Brick-concrete structure: the walls and columns of the vertical load-bearing structure in the building are built with bricks or blocks, and the columns, beams, floors and roof panels are built with reinforced concrete structures. Generally speaking, brick-concrete structures are supported by a small number of reinforced concrete and most brick walls.
3. Steel structure: The main load-bearing structure in the building is made of steel. Suitable for super high-rise buildings. Self-respect is the lightest. The main load-bearing structure is made of steel and reinforced concrete. For example, some beams and columns of a building are mainly steel frames, and some beams and columns are reinforced concrete frames.
4. Reinforced concrete: The main load-bearing structure is generally reinforced concrete. Load-bearing structures such as walls, columns, beams, floors and roof panels are reinforced concrete, and non-load-bearing walls are filled with bricks or other materials. This structure has good seismic performance, strong integrity, strong fire resistance, durability and corrosion resistance. Including thin shell structure, large formwork cast-in-place structure and reinforced concrete constructed by advanced construction methods such as sliding formwork lifting plate.
