Many of China's iconic buildings are steel-framed building，Large-span steel structures are increasingly used in large space public buildings

The construction organization design is the premise of how to install the building reasonably and effectively, and also the design of the quality of the steel structure building and the safety of the construction personnel.

Because of the steel structure advantages ,the steel structure has many applications . It is widely used in many field.

Sustainable buildings different parts are placed on the assembly line of the factory. According to the standard production of steel structures, doors and windows, light bulbs and other 'building parts' shipped to the factory for modular assembly, and then transport these semi-finished 'building parts' to the construction site.

Due to its beautiful appearance, short construction period, high degree of industrialization and resource reuse, the steel structure factory is destined to have a strong construction market share.

Steel structure design is an important part of the whole steel structure construction, from the blue print of steel structure design to the evolution of steel structure products.

In recent years, with the continuous increase of steel structure construction projects around the world, it is urgent for Chinese engineers and technicians to understand and familiarize with European and American norms.

In order to avoid the deformation to ensure the stability and safety of the steel structure, we must take effective fire prevention measures to improve the fire resistance of steel materials.
