1. Definition

Brick-concrete structure is a mixed building structure that uses brick walls to bear the weight, and mixed steel bars, cement, sand, gravel, water and other concrete floor slabs, beams and columns and other components. It is suitable for small bay depth, small room area, multi-story or low-rise buildings.

Steel structure houses refer to buildings that use steel as load-bearing beams and columns. They have light weight, simple construction, and strong resistance to deformation. They are often used to build large-span, super-high, and super-heavy buildings.

2. Characteristics

Brick-concrete structure houses can save steel, can use local materials, and are relatively cheap. At the same time, the construction technology and equipment requirements are not high, and the construction difficulty is relatively low, but they are heavy, poorly stable, and weakly seismic resistant. It is difficult to achieve large-scale multi-story buildings. Some areas also limit the floor height of brick-concrete structure houses.

Steel structure buildings are light in weight and high in strength. Their self-weight is about 1/2 of that of brick-concrete structures. They are safe and reliable, with strong stability and deformation resistance. They are easy to construct and have a short construction period. They are very suitable for factory buildings that require large spaces and are very in line with industrialization requirements. In addition, steel structure buildings are of reliable quality, easy to install and dismantle, recyclable steel, and almost no construction waste is generated. They are low-carbon and environmentally friendly.

3. Cost

The cost of brick-concrete structure houses is generally between 900-1100 yuan per square meter, which will vary depending on the changes in cement, steel bars, and labor costs.

The construction price of steel structure houses includes design, construction, materials, etc. The cost of a single-story steel structure factory is about 200~1000 yuan/square meter. The specific cost also needs to fluctuate according to the different steel prices and labor prices in various regions, as well as specific requirements and design plans, technical requirements, etc.

Steel structure houses are fast to construct and have a short construction period, which is about half the construction period of brick-concrete structures. This greatly saves labor costs and construction costs. In addition, its usable area is also larger than that of brick-concrete houses, generally over 90%, while that of brick-concrete houses is only about 78%.
