The steel structure of the airport is to reduce the weight, so that the span of the airport is larger, the capacity is large, and the flow of people is evacuated quickly. At the same time, the building steel strength is high, the plastic toughness is good, the material is uniform and the mechanical calculation assumption is more in line with, the rigid structure is simple to manufacture, the construction period is short, the steel structure corrosion resistance is poor, the steel structure compactness is good and the steel structure is more seismic, more safe.
