Abstract
Pedestrian bridges are an important part of the urban infrastructure that ensures the safety and comfort of pedestrians. They have a number of distinctive features compared to road bridges. Also, the pedestrian load itself has a significant dynamic component, which can lead to the occurrence of resonant phenomena. Composite reinforced concrete bridges are widely used among the road bridges. This is due to the possibility of including the roadway structure in the act, which increases the load-bearing capacity and reliability of the structure. The same advantages are typical for pedestrian aboveground overpasses. However, pedestrian bridges have a number of features that affect the operation of the composite reinforced concrete structure. It is well-known that the difference between bending structures in civil construction and bending structures in bridge and road construction is the ratio of the rigidness of the concrete and steel parts. The load on pedestrian aboveground overpasses is similar to the temporary load in civil buildings, adjusted for a large dynamic component. But at the same time, the spans of pedestrian aboveground overpasses are similar to the spans of road bridges. In this article, the prospects for the development of composite reinforced concrete structures of pedestrian overpasses are reviewed.
Highlights
Pedestrian bridges are an important part of the urban infrastructure that ensures the safety and comfort of pedestrians
According to the results of the work, the following prospects for the development of composite reinforced concrete structures of pedestrian overpasses were identified: 1. The study of shear connectors traditionally occupies an important place in the study of composite reinforced concrete structures, since it is often the shear strength that provides the load-bearing capacity and reliability of the structure as a whole
Studies of the connectors of composite reinforced concrete structures generally correspond to pedestrian overpasses, but studies on adaptation are required, taking into account the distinctive features
Summary
Pedestrian bridges are an important part of the urban infrastructure that ensures the safety and comfort of pedestrians. They have a number of distinctive features compared to road bridges. The structure of a pedestrian overpass takes up a relatively small pedestrian load, with significant spans, which leads to high slenderness ratio. The pedestrian load itself has a significant dynamic component, which can lead to the occurrence of resonant phenomena [1-6]. Composite reinforced concrete bridges are widely used among the road bridges. This is due to the possibility of including the roadway structure in the act, which increases the loadbearing capacity and reliability of the structure.
