Bridge over Nitra River (case study)
Object description
The bridge was built in 2011 in West-Selenec in Slovakia. It is situated over Nitra River. The bridge is formed of one cell box section. The bridge has a 357,5 m long main bridge over the river and an 807 m long approach viaduct. The main bridge has 5 spans of length from 50,0 to 85,0 metres. The structural system of the bridge consists of steel and concrete. The bridge was built incrementally.
Object analysis
The bridge in the R1 expressway is very important for railway transport In Slovakia. Monitoring of that bridge allows to eliminate all potential damages. All sensors is mounted along bridge. It is related with a heavy height transport moving (e.g. trucks). The case of study is to research all points where it is possible to find some damages of bridge.
Object state
The bridge over Nitra River was constructed generally for expressway road. The most important damage for this bridge is excessive deformation and displacement. It is very important for dynamic behaviour of the bridge. It is used three performance indicator: excessive deformation, displacements and other loads (e.g. temperature). Temperature and overload monitoring allows to reduction risks of the deformation.
