Rural self-built houses, steel structure or brick-concrete structure, which is better?

First of all, as the name implies, except for the main load-bearing structure, the rest are light bricks; Reinforced concrete is a load-bearing wall, and the main wall is poured with reinforced cement, so reinforced concrete should be dominant in seismic stress, and the section of steel structure with the same bearing capacity is the smallest; Under the same section, the bearing capacity of steel structure is the largest. The weight of steel structure is very light. The weight of a six-story light steel residence is only equivalent to that of a four-story brick-concrete structure. The main load-bearing part of brick-concrete structure is brick. Masonry and reinforced concrete are loosely combined. Therefore, it is necessary to add ring beams and structural columns to "hoop" the whole brick wall structure to improve the overall performance of the house. If we compare these two kinds of loads, it is obvious!

However, compared with brick-concrete structure, the cost of steel structure is slightly higher than that of traditional brick-concrete structure. It needs regular maintenance. In brick-concrete buildings, the corrosion resistance of steel is much worse than that of red bricks and concrete. The sound insulation effect is much worse than that of traditional brick-concrete houses. And the steel structure is more expensive.

Moreover, for brick-concrete structure, as long as the ring beam of ordinary brick-concrete structure houses is well done, the seismic capacity of structural columns still exists. Compared with rural areas, brick-concrete structures are generally used in civil buildings with two or three floors, because of low cost and simple and fast construction! Suitable for this two-story and three-story ordinary farmhouse! General basic seismic capacity meets the standard!

However, in non-seismic areas, the seismic performance of light steel structure is better than that of brick-concrete structure. However, the self-built brick-concrete structure is still the first choice in rural areas, which is more economical and has basically good seismic effect. These two structures are the same in normal use. The only difference is that residential buildings adopt brick-concrete structure and public buildings adopt light steel structure, such as large factories, stadiums, super high-rise buildings and other fields.
