General Information
Figure 1 shows a single-span pedestrian overpass.
| Main span | ≅ 28 m |
| Girder | Prestressed concrete I-beam |
| Deck width | ≅ 2 m |
Material Selection
Figure 2 shows the bridge.
The superstructure consists mainly of two prestressed concrete I-girders, four RC diaphragms (two intermediate and two end), and an RC deck. Figure 3 shows a schematic cross-section of the bridge, while figure 4 shows a schematic cross-section of a steel beam bridge variant.
The girder is made of an H-section, the cross frame is of X-type (cross braces), and the deck is made of steel gratings.
Can those factors be weighted differently based on the project's geographical location?
