Which is more expensive, steel structure or concrete building?

Steel structure is widely used in industrial buildings because of its light weight, high strength, large span, flexible layout, short construction period, good seismic performance, environmental protection and high recyclability. Large factories, multi-storey office buildings, shopping malls, hotels, super high-rise buildings.

Brick-concrete structure means that the wall of vertical load-bearing structure in a building is built with bricks or blocks, and the constructional column, transverse load-bearing beam, floor slab and roof slab are built with reinforced concrete structure. Commonly used in ordinary multi-storey houses below 7 floors. Advantages: low cost, simple and fast construction. Disadvantages: it is not suitable for complex architectural forms, and has strict structural requirements such as height and room size, and its seismic capacity is slightly weak.

1, steel structure is superior to brick-concrete structure in terms of firmness. Steel structure housing can build up to ten floors, while brick-concrete structures usually have six floors of ceilings.

2. In terms of cost, according to the current market price, the steel structure house is about 1.200 yuan per square meter, and the brick-concrete structure is even lower, which is about 800 yuan per square meter. The steel structure building completely saves the cost of cement, steel bars and other materials needed for the frame structure, and it also seems to be a big deal in resource utilization. The reuse rate is as high as 90%. Moreover, the construction period of steel structure residence is shorter than that of brick-concrete structure, which can save the owner more than 2/3 of the time, greatly reduce the labor cost and make the owner put into production as soon as possible. On April 1 this year, People's Daily published an article, reporting that two steel structure hotels in Guangzhou were completed in less than five months. If it is a brick-concrete structure, the construction period should be at least 18 months. Obviously, the labor cost of 13 months has been saved, which is not a small sum. In addition, how much income can the owners earn if they start business more than 13 months in advance?

To sum up, compared with brick-concrete structure, steel structure buildings are naturally more cost-effective than brick-concrete structure buildings.
