Box-shape steel girder

High-rise steel structure steel, usually made of steel plate girder, steel truss and minor component

Steel structure building, compared with common reinforced concrete upper loads,

light intensity is high, the ductility, good aseismic performance.

After the investigation results from home and abroad, steel structure building

collapsed few in number. In housing, for example, the steel structure housing

reinforced concrete gravity is about half the residential area, and improve around

4%, The upper loads, reduce the difficulty of working with reduced, Especially the

steel structures in the factory, reliable quality, high precision, easy installation,

short construction, industrialization requirements, Steel can be recycled, the life of

the building demolition of maturity, structure of solid waste, pollution of the

environment.
