Brama Przemyska (case study)
Object description
The bridge was built in 2012. The bridge is situated in Przemysl (South-East Poland) over San River. It has a total length 229,5 m. The bridge had two-span facility (114 m). This bridge is very important for the city (Przemysl). The bypass allows to eliminate transit traffic from the city centre. It facilitates access to the border crossing with Ukraine in Medyka.
Object analysis
The case of study of bridge in Przemysl is to research all points where it is possible to find some damages. 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 measure object displacements. The monitoring system is installed in a few elements of bridge. GNSS antennas and weather stations were installed. 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 San River was constructed generally for roadway use. The most important damage for this bridge is excessive deformation. It is used four performance indicator: angular displacements, displacements of the span and construction deformation. The signal of sensors could monitoring dynamic response. This leads to reduction risks of the deformation.
