Steel-structure pedestrian bridge

The utility model discloses a steel-structure pedestrian bridge. The two ends of a main girder are respectively supported by a first pier column and a second pier column. The main girder is in a consolidation relationship with the first pier column and the second pier column. The connection portion of the first pier column and a first concrete cushion cap is in a consolidated structure, and the connection portion of the second pier column and a second concrete cushion cap is in a hinged structure. The steel-structure pedestrian bridge has a typical ultra-thin girder due to the fact that the depth-span ratio of the steel-structure pedestrian bridge reaches 1/28-1/35, greatly breaks through the conventional depth-span ratio of a simply-support steel box girder pedestrian bridge, which is around 1/20-1/22, meets the landscape requirement of urban pedestrian bridges, and greatly improves the base frequency of the pedestrian bridge structure so that pedestrians feel more safe, stable and conformable. The portal frame pedestrian bridge structure is simple to construct and reliable in force transmission, has good anti-fatigue performance and durability so that the project investment is reduced, the structural design, the construction and the application are more reasonable, the structure has a relatively strong comprehensive economic indicator in a total lifecycle, and the application prospect is broad.
