Abstract:

In Poland, monitoring systems have been installed on large bridges for over 20 years, and the collected results are used to control the condition of the facilities, and in planning maintenance works. The paper presents SHM systems installed in two cable-stayed objects:

  • the Solidarity Bridge in Płock. It is a steel cable-stayed bridge with a main span of 375 m. SHM has been collecting data on this bridge since 2005.

  • Rędziński Bridge in Wrocław. It is a concrete bridge with an unusual structure and spans 50 + 2 x 256 + 50 m. SHM has been collecting data on this bridge since 2011.

    Selected data from the SHM systems will be presented regarding the following:

  • changes of forces in the cables during operation,

  • changes in the geometry of bridges over time,

  • use of monitoring results to develop design recommendations for new bridges.
