Comparison between steel structure and concrete

1, base:

The bearing surface of steel structure building is 20% smaller than that of concrete column, which greatly increases the actual use area of the building.

The steel structure is because the dead weight is reduced, the foundation construction uses less soil, and the damage to land resources is small.

In addition, the consumption of concrete is greatly reduced, which is beneficial to protect the ecological environment.

The steel structure foundation is about half of the concrete structure, which can greatly reduce the foundation cost.

2, the main frame structure:

Compared with ordinary reinforced concrete structure, steel structure has symmetry and high strength, and the strength and elastic modulus of steel are many times higher than that of masonry and concrete. Therefore, under the same load, the bearing capacity of steel structure is lighter than that of concrete building 10%. From the damage point of view, the steel structure has great signs of deformation in advance, which belongs to ductile damage structure, and can detect the danger in advance and avoid it.

3. Building space:

The steel structure bay is 50% larger than the concrete structure bay, which makes the building layout more flexible. The large bay design can divide the indoor space into various schemes to meet the different needs of users.

Industrial production is much more comfortable. Compared with traditional buildings, steel structure residential buildings can better meet the requirements of flexible separation of large rooms in buildings, and the area utilization rate can be improved by reducing the cross-sectional area of columns and using lightweight wallboard, and the effective indoor area can be increased by about 6%.

4, the construction period:

Steel structure is a completely industrialized product, and it is convenient and quick to assemble steel members at the destination after manufacturing.

Concrete construction should consider the weather, site environment, etc.

The construction speed of steel structure is fast, and the construction period is at least one third shorter than that of traditional concrete buildings.

5. Economic benefits:

Compared with concrete buildings, steel structures have advantages in use, design, construction and comprehensive economy, with low cost and can be moved at any time. The steel structure project has the advantages of fast construction speed and small floor space, and is suitable for all-weather construction, and is less affected by climatic conditions.
