General Information
Figure 1 shows a hybrid cable-stayed suspension bridge that is used by motorcycles, bicycles and pedestrians.
Type | Single-span hybrid cable-stayed suspension bridge |
Main span | ≅ 75 m |
Deck width | ≅ 2 m |
Girder | Steel twin I-girder |
Pylon | Reinforced concrete (A-longitudinal shaped) |
Stay cable arrangement | Radial (two cable planes) |
Arrangement of Stay and Hanger Cables
Figure 2 shows a schematic three-dimensional view of the main span.
The main span girder is connected to 6 hanger cables and 16 stay cables. The former have about a constant spacing (s), while the latter have a shorter spacing in the mid-span region, as shown in figure 3.
Fifty percent of the stay cables (8 cables) and two hanger cables are installed in the mid-span region.
Stay Cable Vibration
Figure 4 shows a schematic lateral view of the bridge.
Video 1 shows stay cable 1 during hand-induced vibration.
