Steel structure refers to a structural system that uses steel as the main construction material. It has the following advantages:

High strength and rigidity: Steel has high strength and rigidity, so that the steel structure can withstand large loads and deformations.

Plasticity and toughness: Steel has good plasticity and toughness, which is conducive to the deformation and seismic performance of the structure.

Light weight: Compared with the concrete structure, the steel structure has a higher bearing capacity per unit weight, which reduces the self-weight of the building and saves the foundation cost.

Fast construction speed: The prefabrication and welding of the steel structure can be carried out in the factory, reducing the on-site construction time.

Reusable: Steel can be recycled and reused, which is conducive to sustainable development and environmental protection.
