General Information
Figure 1 shows a suspension bridge that is used by motorcycles, bicycles and pedestrians.

Type | Single-span suspension bridge |
Main span | ≅ 90 m |
Deck width | ≅ 2 m |
Deck width to main span ratio | ≅ 1:45 |
Pylon | Reinforced concrete |
Girder | Timber transverse beam |
Hanger Rods
The hangers are made of steel rods, as shown in figure 2.

Figure 3 shows a hanger rod top region.

The rod top has an open hook; the white arrow represents an axial force F. Figure 4 shows a further hanger rod.

The rod top has a closed hook.
Hanger Rod to Timber Girder Connection
Figure 5 shows a schematic cross-section of the bridge.

Hanger rod and timber girder are connected by an additional rod, washer, and nut. Figure 6 shows a connection between a hanger rod and two side-by-side placed girders viewed from above.

Additional rods 1 and 2 are differently shaped.
Figure 7 shows a further connection.

Figure 8 shows a connection viewed from below.

Timber Condition
Figure 9 shows a main span sector viewed from below.

Vegetation growing on the two girders is noticeable.
Hanger Rod to Timber Girder Connection Failures
Figure 10 shows a main span sector viewed from below.

Due to the connection failures, girders A1 and B1 are not supporting the stringers.
Are those failures affecting the safety of the bridge?
