| Abstract: |
Over the last 20 years big bridges in Poland have been built and equipped in Structural Health Monitoring systems (SHM). One of those objects is the Rędziński Bridge in Wrocław. It is a cable-stayed concrete bridge built along the motorway A8 in 2011. Since this time the SHM has been collecting data from 222 installed sensors. The bridge is outstanding because of its unusual structure: two separate concert box girders are suspended to a single pylon. The connection is made of 160 stay cables – so this is also the most sensitive part of the structure. The first part of the paper concerns the SHM application. In the next part the measured data form the period 2011-2017 are presented, containing comparisons between forces in cables and temperature changes in the whole structure. The third part will include SHM based calculations and simulations with a complex FEM model, to check the measured data and to estimate future measurements. The last part contains the durability assessment calculation for the cable stays. |
