Bridge in Ozimek (case study)

The bridge was renovate in 2010. The bridge is suspension over Mala Panew River in Ozimek. It has a total length 31,5 m and width 6,6 m. The bridge span is single-span facility. Generally this bridge was built in 1827. In 2009 it was decided to renovate it. This bridge is made from iron. The bridge was used as a road bridge until 1938. Then it continued to be used for pedestrian traffic only.

Object analysis

The case of study of bridge in Ozimek 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. 16 string sensors were used to measure rod deformation and rope elongation. 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 strengthening.

Object state

The bridge over Mala Panew River was constructed generally for pedestrian traffic use. The most important damage for this bridge is excessive deformation. It is used two performance indicator: deformation and elongation measurements and chemical properties. The signal of sensors could monitoring dynamic response. This leads to reduction risks of the deformation.
