Steel structure and brick-concrete structure have their own advantages and disadvantages, and the specific selection should be determined according to the specific situation.
The advantages of steel structure are:
one
Light weight: compared with brick-concrete structure, steel structure has light weight, low requirements for foundation bearing capacity, small dead weight of building structure, and saves building materials.
two
Short construction period: the steel structure fabrication and installation speed is fast, which can shorten the construction period and reduce the construction cost.
three
Recyclable: steel structures can be dismantled, relocated and rebuilt, with high recycling value.
four
Strong seismic capacity: the steel structure has good rigidity and strong seismic capacity, which can reduce the impact of earthquake on buildings.
five
The advantages of brick-concrete structure are:
one
Good fire safety: Brick-concrete structure has good fire resistance, and it is not easy to collapse in case of fire, which has a good guarantee for personnel safety.
two
Energy conservation and environmental protection: Brick-concrete structure has good thermal insulation performance, which can reduce energy consumption. At the same time, building materials such as bricks can be recycled, which has good environmental protection performance.
three
Relatively low cost: compared with steel structure, the cost of brick-concrete structure is relatively low, which is applicable to some economical construction projects.
four
Therefore, the selection of steel structure or brick-concrete structure requires comprehensive consideration of the characteristics, purpose, geographical location, environmental requirements, cost budget and other factors of the project. Generally speaking, steel structure can be considered for large-span, high-rise buildings or special-purpose buildings; For some small and simple buildings, brick-concrete structure can be selected.
