Mixed structure does not refer to a single structural form, such as concrete, wood structure and steel structure. It refers to a kind of structure, which is the sum of various structural forms, that is, mixed structure. A structural system composed of two or more load-bearing structures made of different materials is a mixed structure.
Mixed structure refers to a single structure such as concrete, wood structure and steel structure, which is a kind of structure formed by the sum of various structural forms. The most commonly used is a mixture of reinforced concrete and brick and wood.
Extended data:
There are seven types of building structures:
1. Frame structure: The advantages of self-built houses with frame structure are: earthquake resistance level 8, wind resistance level 13, 50% more housing rate than traditional houses, and the integrated houses with 120 months 10 square meters can be built for direct occupancy. Save time and effort. The beam-column members of frame structure are easy to standardize and finalize, and it is convenient to shorten the construction period by adopting assembled integral structure; When the cast-in-place concrete frame is adopted, the integrity and rigidity of the structure are good, and the seismic effect can be achieved if it is designed and handled well, and the beam or column can be cast into various required cross-sectional shapes.
2. Steel structure: The main load-bearing structure is steel, including suspended cable structure. Such as steel factories and large stadiums.
3. Steel and reinforced concrete structure: The main load-bearing structure is made of steel and reinforced concrete. For example, some beams and columns of a house are made of steel frames, while others are made of reinforced concrete frames.
4. Reinforced concrete structure: the main load-bearing structure is reinforced concrete, including thin shell structure, large formwork cast-in-place structure and reinforced concrete constructed by advanced construction methods such as slip form.
5. Mixed structure: the main load-bearing structure adopts reinforced concrete and brick-wood structure. For example, beams of buildings are reinforced concrete, brick walls are load-bearing walls, or beams are made of wood and columns are reinforced concrete. Use precast reinforced concrete thin beams to mix the second class and the rest to mix the first class.
6. Brick-wood structure: The main load-bearing structure is brick-wood structure. For example, a house is made up of wooden frames, brick walls and wooden columns. Gables and front transverse walls on both sides of the house are first-class brick wood with a thickness of more than one brick; The gables on both sides of the house are more than one brick, the front transverse wall is half brick, slab wall, false wall or other single wall, the gable of the wing is one brick, and the front wall of the wing and the front wall of the main house are less than one brick, which is second-class brick wood.
7. Other structures: All building structures that do not belong to the above structures fall into this category.
