With the rapid development of modern cities, the construction of more and more pedestrian Bridges has become an effective measure to solve the safety of pedestrian crossing and alleviate traffic congestion in busy urban junctions. But the past reinforced concrete structure pedestrian bridge, both in the shape of the bridge and in the construction period, compared with steel structure pedestrian bridge are slightly inadequate. The steel structure pedestrian bridge with its beautiful appearance, construction environmental protection fast, high safety advantages, more and more are applied to the construction of Bridges and houses, especially in the case of limited conditions, large span, can only consider the steel structure. Steel structure is characterized by light weight, high strength, and has its compressive, tensile and other related advantages, compared with reinforced concrete structure, its appearance is more intuitive, higher strength grade.
With the rapid development of cities and the rapid expansion of urban population, pedestrian Bridges are widely used in urban construction in order to protect the safety of pedestrian crossing and the needs of public transportation. The steel structure is favored by more and more urban construction groups for its safety performance, reliable design, short construction period, strong economy and green environmental protection, which perfectly meets the needs of urban construction. With the improvement of steel material varieties, further standardization of the industry, these will provide a broader space for the further development of steel structure.
