Which is better, the steel structure or the frame structure?
Brick wall bearing, called brick concrete structureCommonly used in the 7 storey below ordinary multi-storey residentialThe utility model has the advantages of low cost and simple and fast construction.Disadvantages: not suitable for complex forms, floors, room size and other construction requirements strictly, seismic capacity weaker.
The frame structure with partial concrete wall is called frame shear wall structureOften used in high-rise office buildings, shopping malls and hotels.Advantages: the use of indoor space and the partition of the room wall, as flexible as the frame structure. The seismic performance is as strong as that of the pure shear wall structure.Disadvantages: large amount of concrete, from the major, the total height is usually no more than 150m.
Concrete beams and concrete walls are called shear wallsCommonly used in ordinary high-rise residential, and Fangxing very complex multi-storey villas and villas.Advantages: load-bearing structure for sheet concrete wall, the room can not see the edges and corners of columns, more suitable for residential than the frame structure. The concrete wall has the strongest seismic resistance, and the building safety is very high.Disadvantages: large amount of concrete, from the major, the total height is usually no more than 150m. The concrete wall is a high strength load-bearing wall, and the room can not be dismantled.
Concrete beam column load-bearing, called frame structureOften used in multi-storey public buildings below 10, such as office buildings, shopping malls and so on. It is also used in high-rise buildings in non seismic areas.Advantages: large indoor space, can meet the complex forms, strong seismic capacity. The partition of the room can be altered at will.Disadvantages: frame column size is too large, not suitable for civil housing. It's hard to reach more than 7 stories in the earthquake zone.
