What are the advantages and disadvantages of steel structure engineering?

Poor corrosion resistance

But it is heat-resistant and not fire-resistant (it loses its bearing capacity above 600 degrees Celsius).

Brittle fracture may occur at low temperature.

The skeleton of SC is slender, and it swings to some extent under the action of earthquake and wind. For sensitive users, they will feel dizzy and uncomfortable. At present, the popular steel-reinforced buildings with diagonal braces can alleviate the above problems.

The sound insulation effect of a house with SC structure will be poor.

The cost of SC[SS] is higher than that of RC cement structure. The cost of SRC is lower than that of src.

superiority

Steel has high strength, good plasticity and toughness.

Reduce self-esteem

The material is uniform and consistent with the mechanical model.

Simple manufacture and short construction period.

Good sealing, suitable for containers.

Compared with SRC and SC, the strength of steel in space is higher, the component size is smaller than that of concrete, and the floor can have a larger clear height. Because the size of steel columns is relatively small and the actual area is larger, steel can also support a larger column spacing, which makes the room's vision wider.
