IJsselbrug Arnhem (case study)
Object description
IJssel bridge consists of a concrete bridge and two steel bridges. The concrete bridge carries traffic in the direction of Arnhem, the two steel bridges carry traffic in the direction of Westervoort. One steel bridge carries the main carriageway, while the second steel bridge carries the parallel carriageway. Practically, the two steel bridges are identical. Each consists of an approach bridge and the main bridge.
concerning the construction years :
- 1941 Start construction of embankments / abutments
- 1943 Construction halted due to the second World War
- 1961 Opening of the eastern IJssel bridge
- 1964 Opening of the western IJssel bridge
- 1975 Widen both bridges with inspection paths on extended consoles
- 1977 Conservation of the eastern IJssel bridge
- 1985 Restoration of concrete pillars
- 1989 Conservation of the western IJssel bridge
- 1990 Repair concrete deck / scraping edges of both bridges and installation of ZOAB
- 1990 Driving direction
Object analysis
Within this case study, a probabilistic analysis using Bayesian approach were used for reliability analysis of the structures. some of the prior parameters are physical parameters and some of them are model and measurement uncertainties.
Object state
within this case study, the main measurement tests are: 1) strain measurements with strain gauges on the main supporting structure and fatigue details, 2) ballast test, 3) noise measurements / noise source location, These measurement were used to update the partial safety factor.
