Martinus Nijhoffbrug (case study)

The Martinus Nijhoff brigde is a cable-stayed bridge spanning the river De Waal in the Netherlands. The bridge is situated in the highway A2, one of the main north-south highways in the Netherlands. The bridge has in total 3 spans bridge, a total length of 990 m and a main span of 256 m. The bridge had a modular expansion joint. See also https://nl.wikipedia.org/wiki/Martinus_Nijhoffbrug

Object analysis

Based on the measured strains and a comparison of the maximum strains with the strains at previous days, it was decided whether the increase with the previous day was larger than expected. If so, inspections were carried out to determine whether the joint was damaged.

Object state

The state of the structure (focusing on the joint) was that the joint was supposed to be replaced. The monitoring system was installed to postpone replacement of the joint by one year and to reduce the risks related to failure (sliding) of the supports of the separation beams in the expansion joint. The result of failure of the joint during service is related to traffic safety (not to structural safety)

Observed deterioration processes

:

Observed damage types

:

Local rupture or failure, Excessive deformation

Performance indicators
