Tadeusz Mazowiecki Bridge (case study)

-

Object description

The bridge was built in 2015. The bridge is situated in Rzeszow (South-East Poland) over Wislok River. It has a total length 482 m and width 28,5 m. The bridge in a five-span arrangement. The lengths of the spans are: 3 x 30 m, 150 m and 240 m. The cable-stayed structure is supported by a 107-meter A-shaped pylon.

Object analysis

The case of study of bridge in Rzeszow is to research all points where it is possible to find some damages and check some conditions in that bridge. Generally point of initiation of assessments is pure research interest. Monitoring of that bridge allows to eliminate all potential damages in qualitative criteria and design value criteria. All sensors is mounted along the bridge. Designers used 600 m of optical fibres. 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, strengthening or upgrading.

Object state

The bridge over Wislok River was constructed generally for roadway use. The most important damage for this bridge is excessive deformation. It is very important for dynamic behaviour of the bridge. It is used two performance indicator: other loads (e.g. temperature) and span deformation. In this bridge a weather station is also installed. The signal of sensors could monitoring dynamic response. This leads to reduction risks of the deformation.
