Composite Bridge in Nowa Wieś (case study)

The bridge was built in 2016. The bridge is situated in Nowa Wieś (near to Rzeszów) over Czarna stream. It has a total length 10,7 m (single-span facility). The bridge span is made of four composite girders. This bridge is very innovative. The bridge span and beam is made from fibre reinforced polymers. The deck plate is sandwich composite. The core of this composite sandwich is PUR foam.

Object analysis

The bridge in Nowa Wieś is in the road between Rzeszów and Jasionka. The case of study is to research all points where it is possible to find some damages of bridge. Generally point of initiation of assessments is research interest. Monitoring of that bridge allows to eliminate all potential damages in qualitative criteria. All optical fibres sensors is situated in girders. Also very important is structural analysis. In this case it concerns ultimate limit state. The physical intervention of that bridge is repair.

Research

Object state

The bridge over Czarna stream was constructed generally for roadway use. The most important damage for this bridge is local rupture or failure. It is very important for dynamic behaviour of the bridge. It is used three performance indicator: deformation, other loads (e.g. temperature) and acoustic emission. The signal of sensors could monitoring dynamic response or visual inspection. This leads to reduction risks of the deformation.
