General Information
Figure 1 shows a pedestrian suspension bridge.
| Type | Three-span suspension bridge |
| Main span | ≅ 40 m |
| Deck width | ≅ 1.5 m |
| Deck width to main span ratio | ≅ 1:27 |
| Pylon | Reinforced concrete (H-shaped) |
| Girder | Steel truss |
Truss Girder
Figure 2 shows a schematic partial three-dimensional view of a truss girder sector.
The truss girder consists of upper and bottom chords, diagonals, horizontal ties, and cross-braces (red marked); verticals are therefore not applied. The diagonals of side 1 are inclined in the opposite direction to the diagonals of side 2, and the cross-braces are alternately inclined in the opposite direction. Figure 3 shows a side view of a truss girder sector.
The truss girder carries also two pipes.
Main Cables to Pylon Connection Position
Figure 4 shows a pylon viewed from the front.
Enlarged view 1 is shown in figure 5.
The red arrows represent the vertical component forces of the main cables, which are acting on the horizontal braces.
Entrance Elements
Figure 6 shows the bridge entrance on shore 1.
Entrance element A is shown in figure 7.
An entrance element consists of a reinforced concrete column and a steel structure, which is connected to the reinforced concrete column by a base plate and anchor bolts. The main cable passes through the steel structure via a hole.
Hanger Cables to Main Cables Connection
Figure 8 shows a hanger cable to main cable connection.
The hanger cable passes over the main cable, and the U-bolt clamp passes over the hanger cable.
