Soldarności Bridge (case study)


Object description

The bridge was built in 2007. The bridge is situated in Plock over Wisla River. It has a total length 615 m and width 27,5 m. The bridge in a five-span arrangement. The lengths of the spans are: 4 x 60 m and 375 m. Like we can see main span (375 m) is the longest span in Poland for cable-stayed bridge.

Object analysis

The case of study of bridge in Plock is to research all points where it is possible to find some damages. Generally point of initiation of assessments is structural deterioration. Monitoring of that bridge allows to eliminate all potential damages in qualitative criteria. The monitoring system has got two subsystem: observational and premonitory system. Also very important is structural analysis. In this case it concerns ultimate limit state and fatigue limit state. The physical intervention of that bridge is repair or upgrading.

Case type

Object state

The bridge over Wisla River was constructed generally for roadway use. The most important damage for this bridge is excessive deformation and displacements. It is very important for dynamic behaviour of the bridge. It is used four performance indicator: angular displacements, deformation, deflection and other loads (e.g. temperature). The signal of sensors could monitoring dynamic response. This leads to reduction risks of the deformation.
