Compared with brick concrete structure, which kind of building is more cost-effective?

Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and the welding seams, bolts or rivets are usually used to connect the components or parts. Because of its light weight, high strength, large span, flexible layout, short construction period, good seismic performance, high environmental protection and recycling, it has been widely used in industrial buildings such as large-scale factory buildings, high-rise office buildings, shopping malls, hotels and super high-rise buildings.

Brick concrete structure refers to that the walls of vertical load-bearing structures in buildings are built with bricks or blocks, and the structural columns and transverse load-bearing beams, floors, roof slabs, etc. are constructed with reinforced concrete structures. It is commonly used for ordinary multi-storey residential buildings below 7 floors. Advantages: low cost, simple and fast construction. Disadvantages: It is not suitable for complex building methods. The floor height, room size and other structures are strictly required, and the seismic capacity is slightly weak.

1. In terms of firmness, steel structure is better than brick concrete structure. The steel structure house can be built up to ten stories, while the brick concrete structure usually has an upper limit of six stories.

2. In terms of cost, according to the current market price, the cost of steel structure houses is about 1200 yuan per square meter, while that of brick concrete structures is lower, about 800 yuan per square meter. However, the steel structure construction completely saves the cost of cement, reinforcement and other materials required by the frame structure, and the use of resources is also very open. The reuse rate is up to 90%. In addition, the construction period of the steel structure house is shorter than that of the brick concrete structure, which can save more than 2/3 of the time for the owner, greatly reduce the labor cost, and enable the owner to put into production as soon as possible and make an early surplus. On April 1 this year, the People's Daily published an article reporting that two steel structure hotels in Guangzhou were completed within 5 months. If it is a brick concrete structure, the construction period should be at least 18 months. Obviously, the labor cost of more than 13 months has been saved, which is not a small amount. In addition, how much income can the owners earn when operating more than 13 months earlier?

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