Use of STM for Assessment of Rigidity of Örnsköldsvik Bridge under Fatigue Loading

Popis výsledku v původním jazyce

This article focuses on change of rigidity of concrete bridges under cycling loading. The example from Sweden have been studied and used as an example of the proposed method. The properties of a similar bridge structure were tested in this paper. The aimof the experiment is fatigue development. The structure was divided in three parts, which were studied for changes of rigidity. The second state was strut-and-tie modelling. When the important data from STM were gathered, they were used for determination of the change of rigidity of the given part. The third and last part was to determine the new dynamic moments and the deformation of the structure. Each of these testing periods was 5 years. The simplified model changed due to new data to simulate thechange of rigidity of the bridge and the change in internal forces compared to the initial design. The bridge has been tested for periods from 0 to 60 years of the service life.
